Why not?  Dragging in a ton of extra libraries just for one small app is
not a good idea; in fact if fixing the KDE3 version were not an option I
would rather see kbugbuster rewritten for Qt4 only without any KDE
dependencies at all.

Then there is the matter of good integration into the desktop environment;
this is very difficult to do with two different toolkits and will yield a
non-native feel to the resulting application.
