This is a great reply. Thank you for the interesting feedback about a huge number of GUI toolkits. I /thought/ I was experienced with GUI frameworks until I read this post!
I also have a "soft spot" (personal preference) for Qt. Part of that is C++, part of that is small company "makes it big". Their documentation is absolutely first class. They only need to add more screenshots to improve the docs. (Facepalm... really, I should do that myself via PRs on their open source repo!) They should also allow people to submit sample code to demo each class -- or do it themselves. Yes, I know it is a huge burden, but it would serious lower the barrier for entry. So much of enterprise GUI programming is write sample code, inspect GUI, repeat. Modern GUIs are so incredibly complex that nothing can replace a set of tiny demos you can run and test / try different GUI features.
