I am making a GUI for GPG using Ruby and TK. It will be platform independent, as long as you have ruby interpreter. I will post the source here when it's done, it would have been today but my VM fucked up and I lost a few hundred lines of code. I tried to make it as noob friendly as possible and it includes detailed on screen instructions. It will not be full featured but will provide all of the features of GPG that anyone here really uses (key generation, crypto operations, key management). If people like it I may add full functionality and possibly even more features like automatic clipboard encryption etc.
