Hey, several of my favoruite Windows apps are in Qt (e.g. from my WinXP days: "Launchy", and current versions of TweetDeck and Calibre).
Qt-on-Windows runtime installs much like the Visual C++ runtime, and that, for me, is preferable over any app done in Java/Perl/Python, as I don't have to clutter up my system with RTEs (that are all too often supporting a single app)
...and not one annoying "time to update your runtime... AGAIN"
"Send more pigeons"
Ever notice that even the busiest people are never too busy to tell you just how busy they are?
