I use Qt daily, and it uses native widgets in recent versions. Of course, with the exception of X11, because there is no such thing as native widgets (arguably, Qt is one of the major two native toolkits for X11). E.g. in OS X Qt uses Carbon (or Cocoa from 4.5 on).
Maybe there is some misunderstanding. By the "native widgets" I mean Windows Common Controls - buttons, combo boxes, status bars, etc.
This is the note from a Qt developer I was referring to http://labs.trolltech.com/blogs/2007/08/30/say-goodbye-to-flicker-aliens-are-here-to-stay/
And right now I can see (using spy++) I that Qt (4.4.3) applications are using only one native window handle per top level window. There are few more hidden window probably used for worker threads and reserved for stuff like tooltips etc...
That makes me think Qt might be using GDI (DrawEdge, DrawFocusRect, etc.) or Themes API to draw widgets that looks native. But surely they use their own "widget logic".
