How to change guitar chords to banjo chords ????

Here is a great guitar song by Mel Tillis, "A Million Old Goodbyes" and the first verse with it's guitar chords. I'm not sure how to change these guitar chords to banjo chords. Is there a simple method or can someone explain how to go about it?  I've searched all over the net for these chords but no luck. I'm not sure these are even guitar cords and maybe they are piano chords?

C                                  G7

There's a plane out tonight 

          Am                                                 Em

And I swear to you I'm gonna take that flight

C                             F                      C

Please don't you come to see me cry

             Dm                                        G7

You've seen it in a million old goodbyes.

Thanks for any help; Andy
