Brian, There are various libraries that already support drawing spatial data. One of them is Mapnik (which supports symbology and annotation among other things). Take a look at their C++ drawing sample<http://trac.mapnik.org/wiki/ExampleCode>. If you want to draw things in a much lower level, you can also use OpenGL<http://stackoverflow.com/questions/340185/using-gdal-ogr-api-to-read-vector-data-shapefile-how> .
