The chords are very easy, Jennie.

In the key of D, they are:

Oh beautiful st[D]ar of Bethlehem
Shining f[G]ar through shadows di[D]mmed
Giving the life for those who long have g[A]one [E] [A]
Guiding the w[D]ise men on their way
Unto the pl[G]ace where Jesus lay
Oh beautiful st[D]ar of Bethleh[G] em sh[A]ine o[D]n.

I modulate those chords a little but those are the basics.
