I think Qt is great, but because its C++ the bindings just aren&#x27;t there.  Python has excellent bindings but that is a huge project in itself.
If there was a decent C port of Qt then you&#x27;d get support for almost every language (well any one worth its salt) through things like ffi.
I&#x27;m sure going from your favorite language through FFI to some C wrapper around a C++ library isn&#x27;t the most efficient thing in the world, but for UI programming it shouldn&#x27;t matter.
