I'm still reading through those 3 "road to kde devland" blog links in first post, one of them has these links:

Qt 4.4.3: Qt Tutorial
Design patterns in C++ with Qt4
Qt4 tutorial for absolute beginners

Enjoy!

edit:

You also gotta read/follow all the links inside the links etc. for example some additional links from the above:
