I would advice against trying to write your own installer / updater.
This is very difficult to get right, even if you are an expert Mac OS
X developer. It's not just a technical problem, you would also have to
know about the guidelines for where files should be installed on Mac
OS X, how users expect installers to work on Mac OS X, et.c.
I would suggest that you look at one of the existing updaters, like
Sparkle:

Or to Apple's installer:
