It's amazing how bad the options for native UI frameworks are, even without considering cross-platform, more so once you do. Android is actually decent but with caveat it only works on Android... Windows had a decent WPF but then they came up with 5 other framworks that got rebranded and now nobody knows what to use anymore. Is WinUI the latest and greatest there? Wouldn't be cross platform anyway.

Perhaps Unity? But that's more tailored for 3d scenes, rather than UI widgets.

Genuinely looking for suggestions on what is the best choice to pick there.
