Tab translator

here's a shot in the dark....Let's say I come up with a cool melody and wanna hum it into a recording of Garageband to use later on as a guitar part. Does Garageband have a function/feature that can translate that hum into guitar tablature?
I'm not that proficient of a guitarist so trying to find the notes on the fretboard would take a while where as a quick notation/tablature translation of the melody I just recorded would work wonders.
thanks
