The songs REALLY EASY it's all just two chords Gm and D.
I'm not really to sure on the structure but there's only two parts so I'll just tab the 
two parts and you should be able to tell when to play what.

Part A:
e----------------------------------|
b-4-3-------4-3------4-3------4-3--|
g----------------------------------|
d-----5---------5--------0--------0|
a----------------------------------|
e----------------------------------|

Part B:
e----------------------------------|
b-3---------3--------3--------3----|
g-3---------3--------2--------2----|
d-5---------5--------0--------0----|
a----------------------------------|
e----------------------------------|

Enjoy
