Well those flat 7ths always cause problems with conventional guitar chords. But say you were singing it in D, here's one possibility. I've put one bar every /, and written the chords as they change every time you tap your foot.
/DD/DG/DD/AmAm/DD/DG/DA7/DD/
/D7D7/D7G/DD/AmAm/DD/DG/DA7/DD

You might care to modify that a bit round the endings, but that could be a basis.
