Maybe because wxWidgets is garbage DX and UX wise, and Qt isn’t free and doesn’t allow you to reuse web code? One of the value prop of electron is to reuse your web codebase.

How is wxwidgets garbage DX and UX wise? You can literally read the source code and can build the library in 5 minutes, and the UX is native user interface elements of the given platform.

I don't see how reusing web code is an advantage. Web code is for the web. We are talking about a native platform (Windows 11) which has a mature API platform stretching back decades. Why would you need to make it "web"?
