It doesn't matter where on the guitar you play a G C and D. It doesn't matter how high or low in pitch they are. If you are playing these notes:

g-b-d

Then it is a G major chord and is the I chord of the key of G major.

Likewise if you are playing C major (c-e-g) and D major (d-f#-a) chords, then they are the IV and V chords of the key of G major.

If you are trying to make the chords go up or down in pitch then you need to understand inversions. But even that will not change the fact that those three chords (G - C - D) in relation to one another are always I - IV - V.
