If it's a publicly viewable forum then just a bit of PHP to run an SQL Select

(Select * from thread where forumid = 123 order by dateline desc limit 5)

Then more php to loop through the resulting data displaying the thread information as required.

You can create a couple of settings in vbulletin options for the forumid and limit, then use them in the php so you can change the values in your acp.
