From publisher blurb:
What's better than a free online generator? A generator that you can take with you wherever you go, with or without internet. A generator that lets you edit results, save them to a file, or print them directly.
The Pantheon Generator Portable is a standalone version of the incredibly popular Pantheon Generator at Chaotic Shiny. Create diverse, original pantheons with the click of a button.
The generator is written in .NET, so it should work on all recent versions of Windows and quite a few *nix boxes and Macs as well (assuming you have an emulator).
