Starting with Qt and Qtw

Today I downloaded Qt free version (4.6.0) and installed it on my labtop (windows XP). I also downloaded the Qwt plotting library (4.2.0). After installation Qwt does not compile when I open the qwt project in the Qt Creator. The binary examples also do not run because a dll is missing. I already had this problem once when I installed Qt and Qwt on my desktop machine (running Vista). Of course now I cannot remember what I did then to make it run that time. And that is why I decided to start this blog. Just to make my own notes to help me remember these kind of things.

Maybe it will help someone else too.
