Look at it another way, is there any theoretical reason why it shouldn't
work? :-) Please let us know how it goes.

One simple non-tcl hacker (1) description of Insight is: GDB + tcl/tk
interpreter/GUI-environment + extra tcl commands that directly access
GDB internals ([incr tcl] is in there somewhere :-).  ``wish'' is a
binary that just contains the tcl interpreter + tk GUI stuff.  The big
difference between GDBtk (er Insight) and other debuggers like DDD is
that Insight can directly access the internals of GDB (zero CLI
overhead) via those extra tcl commands.  (The other big difference is
that the GUI proper is in a scripting language allowing rapid
customization).

When you run gdb.exe, it (by default) starts up the tcl interpreter
passing it the insight tcl scripts.
