One way to do it (the way I chose to anyway) is to create your website as a PHP site. All of my pages use a php includes for headers and footers and even a right column. I have a single header file and a single footer file that is loaded in all pages. To make my forums "fit" into my website I simply copy my header and footer code into the UBB header/footer inserts in the control panel. The fun part is is modifying your UBB style to match the look of the rest of the site.
I am not a coder either but if you look at the files it's not too hard to figure out how things work. Feel free to look at my site in my signature. Though you wont be able to log in to my forums. It all depends on the complexity of the layout of your site's pages and your forums. I turned off the sidebars to streamline my design.
I looked at your website and it appears to only be a forum at this time. Are you looking to deveolp a website around your forum?
