Windows' standard controls, windows, fonts, etc work completely different
from QT ones. Win32 API exposes a lot of inner-workings of each control. And
lots of applications depend on that. I'm not even talking about how the
pieces fit together.

In short - for most windows apps to work controls have to behave in a very
particular way which dramatically differs from any other toolkit.

And no Wine doesn't just "translates win calls to kernel and X". Wine
re-implements all of the windows' user space on top of X, kernel and other
