You'd need to have a database with the geographical coordinates of the zip codes. Then you'd be able to calculate the distance between them and display only those inside the radius you set.
Or you'd have to link to a service that'll give you the info you need. Don't know if such a service exists though.

If you already have the latitude longitude database, you can go to ZIPCodeWorld's Developers page for sample codes on distance calculation formula.
