Is there an existing utility app or pref pane to accomplish this?

I was able to do this with Better Touch Tool, as Anonymous mentioned. As a test, I set "Single Finger Tap Top Right" of the Trackpad to the pre-defined action "Open Finder." Presto, new Finder window.
I don't know about any utility that can do exactly that.
However, I would recommend using BetterTouchTool to achieve similar effect.
