How convert my Qt projet in KDE project?
It's for this project: http://ultracopier.first-world.info/
How build it after?
Thanks for your help.

In general the first step is to change QApplication into KApplication. At this point your application becomes a KDE application :) Then you can start using other classes from KDE (for instance by trying to exchange "Q" into "K" in class names). As for compiling - for KDE4 you'll need cmake, for KDE3 you'll need auto tools (autoconf/automake).

You can use CMake for KDE3 as well, I'd actually suggest doing this. Less pain all around :)
