There is a similar Linux version of gogo here.

v0.3 - 5 july 11 download gogo.zip (less than 1MB)

Unzip it into any folder, and run gogo.exe. The first time you run it, use tools | Configure to make it locate your Go software.

The source code(Delphi 6) will be released. I'm just tidying it up at present (1 july 2011)
