Dear Maarten,

no, the WMS specification only allows these requests:

-GetCapabilities(must)
-Getmap (must)
-getFeatureinforequest (optional)
-getlegendgraphic (optional)
-getStyle (optional)
-describelayer (optional)**

Have a look at:
http://mapserver.gis.umn.edu/docs/howto/wms_server

For having a scalebar you need a function in your wms-client (optionally 
you may set the scalebar "INIMAGE" but the
result does not look well.... )

Regards, Till
