Arduino BT - suitable or overkill?

I am considering a project whereby I want to use my bluetooth enabled phone (with a suitable app that I will code) as a remote control for a simple momentary toggle control box (approx. 4 - 6 toggles).
After looking around on the net I stumbled across this site and the Arduino BT. Would the BT be suitable for what I described or is there a better solution / product?
