I can't speak for Qt, but GTK+ is not that great outside of the Linux bubble. IMHO, of course.

Qt is not that fun either, at least two years ago. Old style class hierarchies, clunky abstractions and awful build step (QMAKE). It got better with the use of lambdas, no longer necessary to have class to connect to a signal, lambda works as well.

However QML is an improvement. It was a bit quirky to get render the way you wanted and it was not native & look and feel, but maybe have gotten better since I used it. I could imagine that TypeScript + QML could be quite pleasant. Big downside is that the install size of your program is quite big.

They aren't that great in the Linux bubble.

I say that from the developer and the user perspective.

Qt isn't native. They're drawing their own widgets that look close to native - that's why you can theme Qt apps.

Factually incorrect, since Qt uses native widgets when possible. Applying Qt stylesheets usually disables use of the operating system's styling engine, i.e. only then Qt starts drawing the widgets by itself. Widgets that are not part of the native widget assortment are drawn by Qt.

Then what is this blog post about? https://blog.qt.io/blog/2017/02/06/native-look-feel/

Qt Quick Controls which has nothing to with QtWidgets.
