For anyone interested, I've started a set of such bindings here: https://github.com/seaqt/seaqt-gen - the output can be seen here: https://github.com/seaqt/seaqt - the project is based on miqt (go bindings) with the aim to expose as much functionality as possible to C such that it can be imported into any language that has good FFI / C interop capabilities (such as https://nim-lang.org/), though there is of course nothing preventing the use of these bindings from C natively - the generated code is actually pretty simple to follow / use.
