mestaykool, there are a lot of options out there. Virtually all hosts now offer some form of one click script installs which will include forum software.
You should look first for a quality host and make your decision based on that.

Even if that host does not offer control panel installations of software there are many great options out there.
For forum software I recommend SMF (http://www.simplemachines.org) which is in my opinion the best free forum software on the market.
