Best GUI framework for a game editor?

[3DModelerMan]

What does everyone use for their game editors? I'm trying to decide which GUI framework to use for tools. I wrote my engine in Visual C++ Express 2010, and I'd just use the Windows API except that it doesn't have form editor. I've looked into GTK+, Qt, and wxWidgets. What does everyone use?

i really enjoy using qt, you should check it out

I use the standard Irrlicht GUI. I guess just because I'm too lazy to spend time with QT or something else

same here, irrlichts GUI stuff is good enough to get something up and running quickly.

I tried Qt once, I'd recommend it too if you're serious about developing polished cross-platform tools and apps

I'm planning on using VC++ Express. Is the Qt Designer application any good? I really like the features of Qt now that I look closely at them.

there's not a best GUI editor. bu my requisites are:

ease of use.
high maintanability.
relies on std and stl (so using std::string etc.).

for rendering is indifferent. It can use native gui of the OS as opengl. this doesn't matters for me.

Qt Creator/Designer is rather intuitive and it can generate code directly from the layout you designed, the only pain with it is that your code will require a pre-processing step using Qt's moc tool and that creating and adding custom widgets is just a huge mess if you don't write a custom Designer implementation (in my experience, that is)
