action workflow

I'm actually creating a special content type with the cck module. Th problem thereby is that I want to have the discussion to the content not in form of comments but in form of a forum topic. This should be generated for every content of this type by default.

I thought an action maybe in combination with a workflow could help solving this problem fast. I'm not good at php so I'm asking here if this is possible and on how to create such an action.
