The usual translation of "go" into French is aller (sounds like "ah-lay").
On the other hand, if you are asking for the spelling of a hypothetical word that French people would look at and naturally pronounce similarly to how we pronounce the word go (like "aïpade" for iPod), then actually the spelling "go" works just fine. And in fact, that is the spelling they use for the ancient Chinese game of wei-qi, known as go in the West.
