I'd like to create a window with a "pause" button and a large plotting

play with some formulas for generating fractals using random numbers.)

There seems to be a large number of different python GUI libraries,
and I wonder if someone can recommend the easiests one to learn for
this purpose?  (The only python graphics library I've used is PyGame,
which I don't think is the way to go here.)

You could use wxPython. You'll need to create a custom control and
have it paint itself by blitting from a wx.Bitmap, which you'll draw
on by using a wx.MemoryDC and then refreshing the control.

I would probably just use pygame myself. I guess you're avoiding it
because of the requirement for a button, but there are GUI libraries
available for it, or if all you need are a couple of buttons you could
easily roll your own.

Excellent suggestion. I got it to work, but using keypresses (pause,
step, quit) instead of buttons, and a mouse event for letting the user
pick the start point on the screen.
