Hi dylanmorgan - Here is a resource that can help with chords:

However, I get nothing for your chord on their nifty little reverse chord finder.
So, lets dissect your chord note for note and see what sort of critter it might be.
Your chord has these notes; D, G, D, F#.
Let the G be the root. Why? Because it just makes the most sense that way . . . since the other notes all relate to G better than they relate to the Ds or the F#.
So, G=1, D=5, F#=7.
Seems to me that it is almost a Gmaj7 but it is missing the B (which would be the 3rd in the chord).
So, this chord seems to be a Gmaj7 without the third.
Perfectly good chord and if it sounds good in your song, then that is dandy.
