Comment (by pcav):

 There is a problem in PROJ4: there are several datum for EPSG 3003 (and
 others), but in PROJ4 the epsg file does not allow a relation 1:n with
 present format (thanks Markus for clarifying this).
 Currently, users need to define their special SRS, which is cumbersome
 and scary for newbies. GRASS solved it recently:
 http://grass.osgeo.org/screenshots/gui.php#wxpython
 -> Location wizard (geodetic datum selection for EPSG 3003 - Italy
 mainland)
 Would it be feasible to copy the approach and port it to QGIS?
