OMG. This is exactly what I needed. I was searching for a solution since 2
months now. Didn't know about subprocess ... I was looking in the wrong
direction (threading, using another GUI toolkit, ...).
It's the best way to do what I want, making a "plugin" upon an existing app.
No more conflicts between toolkits. I can pass the data I wish to display
through a file, serialized with pickle (I found some tutorials on the web,
after 1 hour I was able to have everything up and running).
So thank you very much !!
