How to install QT 4.6.3 under Windows 7

Hi, I downloaded QT from nokia.qt.com(the version 4.6.3) and at first, I didn't configure it(because I didn't knew it had to be done), added the environment vars and everything worked fine. Then I wanted to try Phonon, so I googled it, and tried configuring it and everything, and since then, everything went downhill, I get lots of errors trying to compile files that I had compiled and runned before. I uninstalled and re-installed QT, configured it in different ways and now I dont seem to get it work. It opens QT Creator and everything, but the code(if Im doing pure code) doesn't compile.

Trying to compile this simple code:
Code:

#include <QtGui> int main(int argc, char *argv[]) { QApplication app(argc, argv); QLabel label("Hello, world!"); label.show(); return app.exec(); }
here's what I get:
Code:

And here are my environment variables:
