This is an old question but if someone still is wondering the same question, I’ll answer this as an update for the previous answer.
The tutorials described in the URL above are still valid, very comprehensive and useful, and there are now also developer guides for mobile and desktop QML development at link: http://www.qt.io/training-materials/. The guides there are very beginner-friendly step-by-step tutorials with clear and comprehensive explanations, so don’t hesitate to check these out too.
EDIT 11.7.2012: There is also now a very nice set of Qt Quick tutorials available in the following address: http://doc.qt.io/qt-4.8/qtquick.html. So if you’re interested in Qt and QML, go check those out!
