Qt is non-standard garbage and going the way of the dinosaur fast. Best bet is to use a Microsoft approved offering, like DXUT.
Considering a whole OpenSource community lives around Qt (KDE), I find such a flamebaity post without any evidence to back it up ... extremely difficult to believe.
It's not really flamebaity, Qt is very difficult to compile/build for Windows platform, has many non-standard tools and code, looks like crap compared to officially approved GUI technologies for Windows and seems to have compatibility issues with Windows 7 and above. For Linux Qt is the one-eyed man in the land of the blind. Everywhere else its just a one-eyed man
I meant also that mouse-based GUIs are going the way of the dinosaur fast.
