[feature] GTk4 and QT support ?

[Fr-Dae]

hello, in futur, do you think you can make a version for support gtk4 and QT ?

Mixing QT and GTK is not good idea, and i know (and love) GTK. So i want to use GTK4.

If you are familiar with Git and building from source, you can check the gtk4 branch at https://github.com/ondratu/formiko/tree/gtk4.
