Am I crazy to think Gtk4 is now a viable cross-platform alternative to Qt?
The Gtk devs have at least given the impression that they want to support other platforms (for example, this talk: youtube.com/watch?v=FB2Y2Wk6FKE or this post: https://discourse.gnome.org/t/is-gtk-4-cross-platform/6144/2). And getting it up and running on Windows with MSYS was pretty easy. It also uses GPU-accelerated rendering if available.
