@baqwas You're welcome.
I have no doubt that you have bragging rights for your RPi-driven farm :-)
If you're very keen to get Qt on your RPi, there are articles that describe how to do it:
This one builds Qt on the RPi itself (which is very feasible on a beefy RPi5): https://www.tal.org/tutorials/building-qt-65-raspberry-pi-raspberry-pi-os
This one cross-compiles Qt on an Ubuntu host for the RPi: https://wiki.qt.io/Cross-Compile_Qt_6_for_Raspberry_Pi
However, there are many many steps involved, and it can be tedious for newbies. I strongly believe you will have a much more enjoyable experience if you start by learning how to write Qt apps directly on desktop Linux.
