Answer 1

Aral Balkan has something that you might enjoy

http://openCountryCodes.appspot.com/

it includes the ISO 3166-1-alpha-2 list in HTML, Python, JavaScript, ActionScript, Flex, JSON and XML

with this, just hook up to Yahoo API and do your magic

See the GeoPlanet user guide: http://developer.yahoo.com/geo/geoplanet/guide/ and http://developer.yahoo.com/geo/geoplanet/guide/api-reference.html#api-countries
