I’m not after fully integrating my forum into my website, would be happy with a basic forum theme just want my website header along the top.

An example of this is: http://www.jfarthing.com/forum/

He has the forum under his header.

How would I go about this?

You could just modify the theme that comes with bbPress. Just change the url in the CSS to your header instead of the WP header.
