KyleFYI, did you also download QT Creator? This is the typical way in which a beginner would interact with Qt, not with Qt Designer directly. It is a file a couple of MB in size available from the Qt downloads page. Then you can access Qt directly from your desktop.
Qt Designer is easy enough to use. What's your problem with it?
I mean, of course integrating the Qt tools into an IDE is a good idea, but you could just use an eclipse plugin if you use eclipse, or a Visual Studio add in for... visual studio. Or whatever. Most IDE's nowadays are extensible, why not use that instead of switching to a new IDE everytime you want to use a new lib?
