Trolltech has never offered Qt 3 for Windows (for free). Only Qt-2.3 had a 
free port for Windows.

You need to recompile the CGALQt library, using "Q..3/Windows Free Edition". 
The CGALQt library shipped with the CGAL installer has been compiled 
using "Qt-3/Windows Commercial Edition", and is not binary compatible with 
your version of Qt-3.

If you do not want to recompile CGALQt, you will need to buy a Qt-3 
commercial 
edition (and a CGAL commercial license too).
