Qt4 differs sufficiently from Qt3 to drive you mad if you try to write
one single program for both versions of Qt, especially if the Qt3
compatibility classes won't get wrapped (the transition from Qt2 to Qt3
was much smoother than the transition from Qt3 to Qt4 will be).

I do not know when Qt4 will replace Qt3 in Linux distributions, but I suppose
that is when KDE is ready for Qt4.  Even then I will wait a little
bit till the bugs have got shaken out.  However, I would like to port PyQwt
to Qt4 as soon as possible, so I will run both versions for at least a
year (probably 2 or 3).
