Qt bindings seem very niche. I don't think I've ever seen a Qt project written in anything but C++ (or QML+JavaScript for simple apps).

Maybe the bindings are good? I just don't know, and I'm suspicious of an approach that seems to be entirely outside of mainstream Qt practice.

PyQt is very good

For QWidgets. If you want to use QtQuick, you're basically using javascript and/or C++ (I'm not personally complaining, I'm comfortable enough in C++). EDIT: seems there's rust bindings for QtQuick too.

You can use QML with PyQt5, instead of using C++ you use Python.

Yes you still write QML.

I stand corrected. Thanks for letting me know!

There are Rust, Go and D bindings to QtQuick afaik.

Yeah, but can you use it for any serious application while knowing 0 C++?

Yes.
