I've worked on this a little more. If I create a file like:

#!/usr/bin/python
import os, subprocess
subprocess.Popen(args=["gnome-terminal",
     "--working-directory=/home/jfb/Documents/Prog/Python/breezygui"])

and execute it, it will take me to the correct directory.  Once there if 
I type in 'source bin/activate' I will get a virtualenv. However I can't 
figure out how to do it from my script.

I have tried adding "--command=source bin/active" to args=
but then I get this error:

There was an error creating the child process for this terminal
Failed to execute child process "source" (No such file or directory)

To check if I could even use "--command=", I added "--command=python" 
and I got a  python session.

Could some one tell me what I need to do to issue the command to setup 
virtualenv?

Thanks,  Jim
