Apparently there is a big difference even in a "Hello world" program .
I mean I also tried to start learning Qt4.0 using the famous official Qt book, C++ GUI Programming with Qt 3 (ISBN 0-13-124072-2), but from the first program in the book (hello world) i received compilation errors. The book is still great because besides the program examples (which i am sure can be easily modified to work in 4.0 also) it gives you great explanation of all related Qt concepts (slots, signals, etc...).

I am also a newbie to Qt and for now I sticked with the great Qt documentation (assistant) and so far so good. Actually not very far but still good )
