I see the GEOS library has a Distance() operator that will test the closest
distance between two geometries, and also, in the C++ API, a
DistanceOp::nearestPoints() method that returns the nearest points on two
passed in geometries.

 From this I imagine you could construct the rest of what you need in a C++
program.  While this should be a relatively easy C++ programming activity,
I will admit that isn't the same as a user oriented tool.
