IMHO, phpnuke sucks
The code that it generates is pretty pathetic.
But looking at the needs of anilmail17 I think he can install phpBB, Gallery, WordPress, etc. and create one main page that has all these links. Don't have those links in the form of a menu or something. But have some big graphic in between and scatter the links appropriately
Get hold of cPanel hosting with fantastico and you can install all these applications with just a few clicks
You can have some header graphic which should put in all these installed applications so that they can all have some similarity in looks
