As said before, a quick and simple solution is to use custom shape.

New diagram type written in C is another option. Reading the code of UML
diagrams seems to me a good start,
http://git.gnome.org/browse/dia/tree/objects/UML/class.c is quite
complete :) Take in account that "building Dia plug-ins outside of the
tree is not supported." (See
http://mail.gnome.org/archives/dia-list/2011-September/msg00035.html)

Custom shape should be sufficient if you don't need to customize the
properties dialog. You could create a specific dialog with pygtk but it
will not be well integrated (see group_props.py).

Depending on your needs, maybe another completely different solution is
best suited to solve your problem, for example using
http://wiki.eclipse.org/GEF_Description (interesting example here:
http://www.vainolo.com/tutorials/).
