If you just want to avoid prototyping, you van get the spark fun spectrum analyzer shield and, while you'd be under utilizing it, it would work.   Alternate,y, if you want to use ONLY software, you can use Processing.  There is a vu meter in the demos as I recall that you can use.   Just steal the values at the point where they're about tobe printed on th e window and send them via serial to the arduino.
