I don't know who would willingly pick Qt to do anything. It's a massive pain in the ass to use, the licensing is expensive and convoluted, and it codes like you're 20 years behind. The IDE is junk, the tooling is garbage, the slightest version shift breaks compatibility, the library conflicts with same names of objects, etc...

Qt is my new practical joke for engineers complaining about how bad they have it in their current stack.

Linux really needs a better UI framework because all other platforms are better and faster to implement in native languages/apis.
