Probably the simplest way to do it would be to just create 
multiple tree walkers that you run in turn, each one creating one 
of the outputs.

Otherwise you could use a single tree walker and write multiple 
sets of output to different streams.  I'm not sure if this is 
compatible with use of StringTemplate, though.

I thought there was an example somewhere demonstrating writing out 
.c files together with .h files, but I can't find it at the moment.
