Puneet, I would add that there is a lot of other metadata that you need to set on a map in order to get WxS services like WMS working. If you haven't done that either you are going to be frustrated.
I would suggest getting your script working initially with an actual mapfile and then if you really want to construct the map programmatically use that as a guide.
