This was my first contact with qt, respective kde. I wrote a standalone-gui as well as a widget for the kde-desktop.
The app sends sms via urllib2 (so website-like) and is easy extendable by pluins.
Thanks to my educationcompany Puzzle for the permission to make that public.
Wont work at the moment, at least not for full.. Widget maybe do. Using python2, need rewrite!
