PHPBB with wordpress ?

I think this would be the right place to ask .. if not then MODs please shift my post accordingly ..

I use a wordpress blog .. and i wanted to put a forum on it .. phpbb is my first and last choice anyday .. but i am quiet a n00b at php code …

Is there a way to integrate the forum with the wordpress blog ? and even use its user DB for wordpress too ? .. I installed a plugin recently for a gallery .. and the only thing that required me to do was to make a new page and put a one line php code in it so it shows the gallery. Is it something similar .. or is it too complicated ?

Thankx in advance
Regards.
