Okay, here is my 2 cents about the matter.

I don't like Qt. However, I like GTK and stuff even less, because there is no viable development environment for them.
Qt Creator just barely passes my requirements, and there is no IDE that supports Hildon/GTK development on Windows, sorry, so it is out of the question for me.

It makes no sense that you don't like Qt because it uses C++. You know, they actually TEACH C++ at school. If you didn't get it, it is your loss.
I would anytime prefer a C++-based environment. (However, my favourite language of choice would be C#.)

By the way, GTK+ WILL remain an official toolkit for Meego because Moblin already uses it, so no complaints there.
