Basically im writing an acoustic song, but since its so much different then electric, im not quite sure what chords sound good...or progressions for that matter.
Yes i know about Major and minors...im not retarded >.> But help me please...Im still trying to lean towards rock though, so um yea

G, C, and D. Throw Am and Em in there if you wish... you can alternate D and Dm as well. That ALWAYS sounds good. You would be shocked at how many songs use this one set of chords in so many new ways.

Well there are hundreds of good, famous acoustic rock songs written with open chords, and it would be very easy to imitate them, however you probably ought to try some different chords. Barre chords are a place to start, alternatively you could read up on your music theory and learn all the different types of chords.
