No, there are only problems when you legally want to use GPL'd Python
modules with it and want to distribute the result of your effort.
There is a "free for noncommercial use" edition of Qt/win32 that
should be fine for most in-house projects and for most other use
cases, too.

Qt/X11 is available under the GPL, which might be an ok license for
many people. Those that don't find the GPL and its implications
acceptable can buy a commercial Qt license. AFAIR, for PyQt use, the
Blackadder IDE includes such a license.

We had that discussion recently. If your algorithm isn't bad, it's
very unlikely that a GUI toolkit will be "too slow". Unless it is
Swing or maybe Tkinter ;-)

Define "fast". PyGTK loads a lot faster than wxPython or PyQt. AFAIC,
this is because PyQt and wxPython wrap _all_ of a very large toolkit,
that both (wxWindows and Qt) even include a lot of non-GUI stuff. This
might be solved by trying to split the one shared library into many
small ones, that are loaded on demand.
