If you want to draw lat/longs you may try using a graticule.  There is one 
in jira that we've been bad about incorporating into geotools, but it's 
available in jira. http://jira.codehaus.org/browse/GEOT-600  I havven't 
tried it, and it'd be nice to get feedback if ou do use it.  But I think 
it takes a set of spacings (like lat/long) and generates the grid lines as 
a set of features.
