Most forum software distros tend to be fairly idiot proof. (For me that meant I had to read some instructions, but it could have been worse)
So generally speaking, the hardest part would seem to be setting up PHP/MySQL (as it seems to be the defacto standard for most forum scripts/whatever)
So I would sincerely suggest Apache like everyone else has been saying, but if its on a personal computer, that could keep you from being able to use your own computer...
