Postcode distance calculation with Google Maps

Job Description

I would like to develop a tool that would allow me to calculate distances between two UK postcodes using Google Maps API.
I need to create a database of homes (ideally with SQL server) and the tool would calculate the distances between an inputted postcode and all the homes in the database. The output should be presented in a table, sorted by distance, from shortest to longest.
Please see attachment for detailed information and mock-up.

I would need the interface to connect with the Google API and a XML files through Webservice.

Thanks,
