This is possible, but maybe not needed since those information are already 
available in the EPSG database? The database has a "Domain of validity" 
information as a geographic bounding box; GeoTools among other parses and can 
use this information. The user friendly name is also provided in the EPSG 
database (there is a column for that in the CRS table). A JComboBox filled with 
those information is already provided in GeoTools...
