I am needing to write a simple (I think) program/script that takes a coordinate pair as input, queries a raster at those coordinates, and returns the raster's value at that point.  I would prefer to use Python, but I am open to better suggestions. 
Is this possible to do using any of FWtools or GDAL's utility programs?  If it's possible, could someone write a very brief list of the sequence of suggested steps?  Any help would be greatly appreciated.  Thanks in advance.
