This seems to be a problem with most naivly written wigdets which store
their data in some internal format. What I have done several times is
writing my own widgets. This is possible for Tkinter by using Fredrik
Lundh's WCK (Widget Construction Kit)
http://effbot.org/zone/wck.htm
He has some tutorials and the whole thing is well integrated in Tkinter. He
especially has a tutorial on using HUGE datasets.

Of course you have to undergo some programming for all the features you
would want to use in your text widget. (Highliting, linebreaks,..etc)

I implemented a binary editor some time ago, which is extremely fast with
even a 100 MB file. (For I/O it used memory mapped files, but this is not
the reason it is fast; it just simplified the programmin :-))
