Do not use sheet music. This is an instrument, like the harmonica, which is best learned "by ear."
Some suggestions:
Barbara Allen (slow)
A-Rovin' (fast)
All Through the Night (slow)
Bang Lulu (fast)
Sweet Betsy From Pike (waltz)
Blow the Man Down
Sailor Shantys

Your melody will be played with the right hand buttons. The left hand will supply a deeper note, for harmony. At this point, only use one button at a time in the left, which will probably be for a Waltz: C/GG, G/DD, and F/CC.
Start by playing a scale from the "home-key" (indented, using index) Up and down, down and up. Then go to SIMPLE harmony.

Work out the melody first. Memorize it. Add the harmony. Keep it simple. Have fun....!
