I write native GUIs in GTK using Julia at the moment. Julia is one of the most modern languages you can use today. Multiple-dispatch, very functional, modern package management and virtual environments, high performance, modern sophisticated REPL environment. GTK is quite nice as Glade is one of the nicer GUI designers.

Here is a simple Julia GTK project on GitHub: https://github.com/ordovician/RocketBuilder.jl

Some articles I wrote related to GTK programming with Julia and GTK in general:

- Understanding GTK Layouts: https://itnext.io/understanding-gtk-layouts-13e5a36256fa

- Hiccups Writing GTK3 GUI Code in Julia: https://towardsdev.com/hiccups-writing-gtk3-gui-code-in-juli...

If Julia is not your cup of tea then GTK can be used with Go and Swift as well.

Have you tried / had good luck doing static compilation of Gtk applications?

The big problem with GTK is backwards compatibility or, more precisely, the lack of it. I don't know how it has or hasn't impacted your own work, but I would hold off on recommending GTK to OP unless he/she is aware of this caveat.

Does GTK run on windows and macOS also?
