How about creating a code phrase that can be used (on the HTML) edit page which causes the popular posts to be inserted?
Folks who aren't technically adept might appreciate not having to create a new 'template'. Instead they just insert the code phrase on a blank page. Then, when that page is displayed, the popular posts info appears.
Another plugin, subpage listing, does this. Their code phrase is <!–%subpages%–>
The underlying software translates that phrase into the php code call that the popular posts plugin already has.
