PHPBB Help required, how can i achieve this. Surely its easy?

[Vini]

Im wanting to achieve the below:

[img src=\"http://www.vini.co.uk/uploads/forumpress.jpg\" border=\"0\" alt=\"IPB Image\" /]

[code=php:0]<?php
/*
Template Name: Forum
*/
?>

<?php get_header(); ?>
<div id="main">

<<<< INSERT FORUM INCLUDE?? CODE?? WHAT?? >>>>

</div>
<?php get_footer(); ?>
<?php get_sidebar(); ?>



</body>
</html>
[/code]

the above, is a blank template for my wordpress theme, is there anything i could include in there to get the forum looking like the picture?

an iframe does the job i want, but iframes are rubbish. i dont want the scroll bars and hassle that they bring.

ive tried an include but all the links and css goes to pot for the forum.

any ideas on a way to do this? people have mentioned <div> but never gone into detail.

i must admit i know nothing when it comes to this kind of coding, so need someone to hold my hand/show me a sample/go into stupidly deep detail :(
