I don't disagree that Dia (done in awhile?) isn't a true modelling tool
as it has no information about the relationships between the "blobs" it
puts on the screen, except possibly to rubber-band connections when said
blobs are moved... but it's a start.
"There is also a program available for Dia called Dia2code, which will
convert Dia UML diagrams into C++ or Java code for you."
Alas, python isn't mentioned - but it could be! :)

Good stuff Argo - only mildy hindered by being in java...
