You don't say which language you are creating the debugger for, but note
that there is already a plugin front end for gdb which supports C,C++,
Pascal, Ada, Fortran etc.

Looking at the source of that plugin may help provide you with a known
working outline of a debugger plugin (or save the effort if its a gdb
supported language)
