WordPress MU

Hey everyone,
I would like to create a widget that contains only this code, nothing fancy, or anything, just this code:

<h2>Friends</h2>

<?php list_friends('display', '
• ', '
• '); ?>

Could the header be changed so it fits with the CSS? I tried doing it myself, but it didn't work, so any help here?

Header in most themes are usually list items, <li> .
