most of them are qt based tbh but there are some or I can say lots of dick shits like qt
i would say gtk and wxwidget are the best compare to alternative way for qt
i started off with qt and still using it and tbh best gui ever for c++ but if u want some handling and much ez shit ass wxwidget ,
Note that for using wxwidget, ur desktop needs to run on dx11 so basically one of the problem is if u give the program to some1 that dx11 is not supported on his des it will look like an alien dick
basically wxwidget is based on gtk+ but with better shit and better stuff like fooking gtk+ is super hard to understand fuck it and fuck u
talking about this , I would recommend u using QT but not the free version cz it sucks
I don't see any issue with qt
you can consider these as well : ultimate ++ , fltk , gtkmm ( gtk+ updated haven't used so idk )
you can find the big list on reddedit as well and some argues about good and bad
