QtWvdialer is a simple graphical front-end to wvdial and it's free software. You need the Qt library version 2.1.0 or better and wvdial. It provides you with a easy to use GUI to fire up a ppp connection. Additionally you have access to the output of wvdial, some PPP statistics and a editor for the wvdial configuration. The code for PPP statistics retrieval was extracted from the very fine program kpppload from Sean Vyain. Thanks Sean, for this nice piece of GPL'ed code!
