It's called SciCos, and as far as I've seen it not only covers Simulink
but also PowerSim.

I found only 1 major disadvantage inSciLab, ...
... it has no ActiveX

Why not use an installer to bundle the python interpreter (with TKinter) and
your code in a single executable file? If you don't want to distribute
source code then .pyc or .pyo files can be used?

An example of (freeware) installer software:

(http://www.python.org/download/releases/2.2.2/NEWS.txt):

The signal module now supports SIGBREAK on Windows, thanks to Steven
Scott.  Note that SIGBREAK is unique to Windows.  The default SIGBREAK
action remains to call Win32 ExitProcess().  This can be changed via
signal.signal().  For example:

# Make Ctrl+Break raise KeyboardInterrupt, like Python's default Ctrl+C
# (SIGINT) behavior.
import signal
signal.signal(signal.SIGBREAK,
  signal.default_int_handler)

try:
while 1:
pass
except KeyboardInterrupt:
# We get here on Ctrl+C or Ctrl+Break now; if we had not changed
# SIGBREAK, only on Ctrl+C (and Ctrl+Break would terminate the
# program without the possibility for any Python-level cleanup).
print "Clean exit"

I.M.H.O. anyone that is not capable to grasp the concept of regular
expressions should not attempt to write computer programs at all! My
suggestion to you would be to find a job that involves working with your
hands...
