Not a seperate program, but there are many companies selling templates for use with photoshop with all sorts of great graphics. You can see some at http://www.desktopdarkroom.com
under "templates" and more from a company like http://www.waykewl.com
Also be sure to check http://www.ebay.com
and do a search for "photoshop templates -web" to see several choices.
Pretty simple stuff to use - drag and drop and add some type in most cases and they look awesome in the kids eyes...:-)
