Why C++?

I 'd prefer it if automagically such a binding was announced :-).

Well, that's what everybody count for.

If Jambi generator sources are available, we could take a look and see whether we can make it emit D code and use QtC, but I think that the biggest problem is how to make Qt/D API blend naturally with D and how to replace moc, uic and rcc.

As for Trolltech for me they made the right decision in using C++ as it can be extended to more productive languages (such as ruby or python) and they can use the most powerful language to provide the best available gui toolkit around.

Also there wasn't much choice at the time they started planning Qt.
