I started working with QT recently. The last time I started working with QT was several years ago. And my experience with it wasnt that great.
Now I have started working with the QT IDE and have really enjoyed it. The QT IDE is by far the best IDE I have worked with. The layout is better than the eclipse layout
Here is how to get a QT IDE
Use the LGPL license, but its 380 MB to download.
Also QT can be integrated with eclipse
I have started developing some simple applications using QT. I will keep you updated on the experience
