Ask HN: Best cross platform desktop application framework thats not electron?

Haven't been following it recently, but probably https://proton-native.js.org/#/ or Qt.

Qt/QML is the obvious choice. Xojo is another option.

I went for GTK3 in Go (Gotk3) and kind of regret it. Not that there is anything particularly wrong with it, but I'd go for Qt if I could start afresh.
