You cannot compile PyQt with the qt.dll that might have received
with another application: you need header files for that. To write an app 
and redistribute it using the runtime components received with another 
application written using BlackAdder, might be quite illegal, I think. So 
you cannot get developing with PyQt with just any Qt-based Windows 
app or BlackAdder developed app on your machine.

On the other hand, if you can get the GPL version of Qt to compile on 
Windows (which should not be a too arduous task, merely redoing all the 
low-level stuff like drawing, network code, threading and stuff, nothing
special, really), then you can compile PyQt and distribute the result 
without any problems.

As for me, I only see Windows when my children want to play Levende Letter 
or other educational games, so I'm quite satisfied with Qt, Qt Designer
and PyQt ;-).
