You could try the article below. It isn't software but there is logic in it. Would I use it? Probably not. Learn to polar align it really isn't that hard. It is a little daunting initially but not that bad once you get the hang of it.
http://www.astrophotoinsight.com/node/568 it is written for the northeners so replace references to South with North. I wouldn't start with 2 minute exposures, try 30 or 40 seconds and then go longer otherwise it will take forever and I would still put a reticle in it at the end just to see how close you get.
