    Do you have the code ready, with a .pro file (it is a project definition file that Qt uses to compile applications)? If yes, then you can compile your project from the command line. Open cmd.exe (I guess you are on Windows operating system) and type:

    qmake yourprojectname.pro
    make
    

    That should be enough, assuming your environment is prepared (qmake and compiler are both set up in PATH system variable).

    As a side note, as far as I know there is an accessibility team working at Qt Company, I'm sure they will be happy to hear how both Qt and Qt Creator can be improved to help blind people. You can try reaching them at qt-creator@qt-project.org. You can also subscribe to Qt Creator mailing list here: http://lists.qt-project.org/mailman/listinfo/qt-creator.

      So you can compile it already?
      Or is it the compiling part that is hard to do ?

      Can the JAWS read a command prompt ?

      I can make the source code, it's the compiling the finished program part that's hard. Yes, JAWS can read a Command Prompt. What do I do in there?

        Hi, you will need to create a .pro file which gives instructions on how to build your application. http://doc.qt.io/qt-4.8/qmake-project-files.html

        Once you have have this. you can do as instructed by @sierdzio in CMD.

          @Annabelle Sorry, I was at work when I made my initial response to this thread. A more elaborate answer for you follows as I take it you are beginning in Qt and it may be difficult for you to look up resources.

          Given the scope of your project I think it will suffice to use a simple Qmake project file such as:

          myapp.pro

          TEMPLATE = app
          
          QT += widgets
          
          SOURCES += main.cpp \
              MainWindow.cpp \
              SpouseWidget.cpp
          
          HEADERS += \
              MainWindow.h \
              SpouswWidget.h
          
          OTHER_FILES += \
              anyotherfile.png
          

          You may need to make changes to this in order to fit the needs of your project, but this should be a good enough example for you.

          Once you have this in place, you can open up your favorite Command Line Interface (eg. cmd.exe for Windows).

          Type:

          qmake myapp.pro
          make
          

          Your compiler will generate a binary file for your application at this point.

          I hope this helps,
          Have fun.

            Another thing I'd like to do is make icons for the push buttons, radio buttons, combo boxes, and checkboxes. I'd like to find out, is it OK for me to use unicode symbols as icons? For example:
            In the welcome screen, there are the following Radio Buttons
            ⚭ (Wedding Ceremony Radio Button)
            ~β›² (Baptism Ceremony Radio Button)
            β›Ό (Funeral Ceremony Radio Button)
            For the Spouse Genders, there should be the following Icons:
            πŸ‘° (Bride Radio Button)
            🀡 (Groom Radio Button)
            For the Baptism Person Types, there should be the following Icons:
            πŸ‘¦πŸ‘ΆπŸ‘§ (Infant Radio Button)
            πŸ‘¦πŸ‘§ (Child Radio Button)
            πŸ‘¦πŸ‘¨πŸ‘§πŸ‘© (Youth Radio Button)
            πŸ‘¨πŸ‘΄πŸ‘©πŸ‘΅ (Adult Radio Button)
            For the Funeral Ceremony Types, there should be the following icons:
            ⚰ (Funeral Radio Button)
            ⚱ (Memorial Service Radio Button)
            Note that some of the icons are composed of two or more unicode characters put together, as I couldn't find separate unicode symbols to represent them.

              You should be able to use QString::fromUtf8() for this: http://doc.qt.io/qt-5/qstring.html#fromUtf8

                Could you please be so kind as to give me an example of what one of my icons would look like with the QString::fromUtf8() code? For example: πŸ‘¦πŸ‘ΆπŸ‘§

                  Sure. I'm not sure exactly what you mean. Do you want an image or a code example? either way I whipped up a quick example to demonstrate what it would look like. Here's an image.

                  0_1506120620297_annabelle.png

                  Given that your first post mentioned you where visually impaired, I think I may have misunderstood your meaning, so here's an example in code:

                    QRadioButton* rb = new QRadioButton();
                    QString str = QString::fromUtf8("<Utf-8 code> Button Name");
                    rb->setText(str);
                  

                  Where <Utf-8 code> = the character you wish to display.
                  Pretty sure there is a nicer way to do it. But I'm off to bed. That should get you started though.

                    So are you thinking I should write something like:
                    QRadioButton* rb = new QRadioButton();
                    QString str = QString::fromUtf8("<πŸ‘°> Button Name");
                    rb->setText(str);
                    And for "Button Name", would it be something like:
                    QRadioButton* rb = new QRadioButton();
                    QString str = QString::fromUtf8("<πŸ‘°> Bride");
                    rb->setText(str);
                    Something along those lines?

                      Yeah that will work. But remove the <> from around your unicode character. I only placed them their as placeholder. It will work by placing the unicode character in your source file as you have done, but I would recommend finding the value for it instead. I'm replying from my phone so I can't look ot up for you.

                        By value, do you mean the Unicode value? Or do you mean the hexidecimal value? I'm confused!

                          Sorry, I wasn't too clear. You should use the UCN for example: '\u2639' will represent ☹
                          There can be problems with this as compilers are required to support only the basic source characters. I'm not sure if Qt gives you much help in way of UCN's so if it doesn't display the character for you, use the literal '☹' in your source, and perhaps see if someone else can help you with the use of UCN as I'm not so sure without reading up on it. Perhaps also try reading up on character sets to understand encodings.

                          Edit:
                          I just checked up the code for πŸ‘§

                                That's right. You've got it.

                                So would this look right?

                                QString str1 = QString::fromUtf8("\U0001F470 Button 1");
                                -> Set Text = "Bride";
                                Not quite sure how to do the "Set Text" part, so I did the best I could when writing the code. So how would I compile the full version of the radio button? Would it look something like this?
                                QRadioButton *button = new QRadioButton ("Bride", this);
                                QString str1 = QString::fromUtf8("\U0001F470 Button 1");
                                -> Set Text = "Bride";

                                  QRadioButton* button = new QRadioButton();
                                  QString str1 = QString::fromUtf8("\U0001F470 Bride");
                                  button->setText(str1);
                                  

                                  I would suggest reading a book to get yourself better acquainted with C++. Otherwise you will encounter many pitfalls.

                                    Are there any books out there that are available in Braille? Since that's the primary format which I read. If that's not possible, is there a .chm help file that can explain the language in detail?

                                      It may be difficult to find such a technical book in Braille. I had a look but came up empty. You can find a copy of "C++ gui programming with qt4 2nd edition" in .chm.

                                      I think your screen reader should be ok to read epub? If so you could pickup most textbooks from amazon or something.

                                        I tried searching for the .chm file "C++ gui programming with qt4 2nd
