I understand what Wouter was asking, however the request (to which he
happened to respond) was for "translating gpsim to Java".

But whatever the request may be, there are dozens of ways one can
interface with gpsim. First there is the gui. I presume that the request
for Java was in some part associated with dispensing with that interface.
Then there's a CLI interface  (invoke gpsim with the --cli option and your
freed of all those ostentatious windows). Then there's a module interface.
That's primarily intended as a slave interface, but with a couple lines of
clever code the roles are easily swapped. Then there's the library
interface. gpsim is built as a series of modular libraries that are
dynamically linked. One could just as well write another frontend that
links in with the simulation engine to create a custom interface.

All of these interfaces theoretically require no code changes to gpsim. If
you wish to modify the gpsim source, then there are numerous other ways to
interface.

In practice, I'm certain code would have to be added to pacify some new
interface need.  But as it stands now, one could use Tcl, python, perl, or
whatever script glue desired to create a custom PIC simulator. The only
hurdle I see is time.
