 Of course they can, you just need to try harder :). The same applies to 
your 'extra daemon' and probably 'bad integration' from your other mail (not 
sure about the second one, what did you have in mind specifically?). Ok, 
maybe not completely, but to a sufficient level, I have some proof-of-concept 
code somewhere that can do things like 
http://ktown.kde.org/~seli/download/qtkde/scribus_gettext.png (Scribus is 
Qt-only).

 I'm mainly asking because of the external filedialog because of 
interoperability/kde3vs4compatibility/whatever ideas from Malaga. If you 
remember please CC me on the commit of the abstract interface, I'd like to 
check if there isn't some obvious problem that'd prevent this in the future 
if it ever becomes more than just theory.
