In that case, it's time to seriously reconsider using tabs. Tabs are fine
when there's only three or four logical ones, but when you don't even know
what you're going to have in the future they're pure poison.
The most general replacement for them is a tree control; however, tree
controls are hard to build and use, and if you can fit your choices neatly
into a list your users will be much happier. There are some screenshots
of how to do it right and wrong at <URL

I suppose you're using Tkinter; I'm not familiar with that. The toolkits
I know about use objects, not classes, and you HAVE to have one per page.

Before you do this, though, consider something else. ANYTHING else.
