I wrote a little PyQt4 GUI around the pydownloader code, which was not user friendly enough for me.
All the code has been adapted to fit in a GUI environment.
It's been tested on linux and win... but report here if you see bugs.
I also would like to have the names of the authors of pydownloader both to give them credit and to get their position about the license they place their code under (some kind of GPL I hope

Enough talking, many more info after the link :
