I don't think you'll find any airport data for free, anything comprehensive that is. Companies like Acukwik or Janes charge thousands for theirs as it takes huge amounts of time and effort to keep it accurate and up to date.
If you just need it for reference, eg looking up info then there's plenty of web-based resources and there's an iPhone app with FBO, Airport and Catering info for Europe I know of thru F'book, called SKY Tally.
