You can use a pitch pipe to get the right notes. But the tuning and order of the strings is different. For a guitar it is E A D G B E. For a violin it is G D A E.

It's not impossible to tune your guitar without one, but it is extremely difficult to tune it with the accuracy that an auto tuner will give. A guitar that's out of tune will sound awful even when being played brilliantly.
