Well, I can't speak for other frameworks, but C++/Qt is very much likely to be worth your time at some point.

In general, it's well written and well-documented. Many things you expect that will be hard to do in C++ are suddenly made easy. Just go through some of their small examples to get a gist of signals/slots, QObjects and QWidgets. If you're struggling with CMake I would recommend to stick with .pro files ("qmake") as the syntax is much, much less of a headache.
