Calculate Distance and Choose Closest Location

This module consist of 4 parts: 1. user enters their physical location; 2. system takes airport codes from my system (for user state and ajoining states) and calculates distance from user location; 3. system presents closest airport to user; 4. system presents 3 next alternatives ranked by distance to user location. There are many free webservices that we could use for calculation. Interested in your thoughts on how you would execute (i.e MapQuest API, Google Local API) My database is MySQL. I prefer Ruby but Ajax or straight PHP is fine.
