Chip,

This can be accomplished with OGR using the .csv (or ODBC) reader
along with the VRT driver and the shapefile writer.  The idea being that
the.csv or ODBC reader can access non-spatial input tables, the VRT
driver (along with an XML description file) indicates which columns to
use for X and Y, and then the result is written with the shapefile writer.

The only tricky part of this process is preparing the VRT file.  Then use
the ogr2ogr utility to do the translation.
