Grab city names and lat/long +

I need a script or program, in whatever language you want, that: 1) grabs the full list of municipalities (city, town, villages) names of USA (for single states), Canada, UK, Germany, France, Italy, Spain, Australia, from Wikipedia; 2) gets their latitude/longitude from Google Maps. Note: queries for USA municipalities must indicate the state too (e.g. "Sayreville, NJ, USA") for increased precision. The others must be in the form "Rome, Italy"; 3) create a table, one for each state (country or US state), of the straight-line distances from each of them to each of them, using this ready algorithm [login to view URL] (or another that takes into account the actual polar flattening of the earth and the equatorial bulge...) Full source code and ownership required. Escrow offered.
