You might install Postgis to implement very powerful spatial functionality that can easily do what you are asking (plus a whole lot more).
indeed, PostGIS is the logical answer, but the OP specifically stated he wanted the functionality without 'sophisticated geographic systems'. so I ignored the question.
the alternative would be implementing your own spherical geometry functions, and hook them up to GiST indexing, its not
that hard, but by the time you got all the functionality you need, you'd be half way to PostGIS, so why fight it?
