Thanks for the suggestions, everyone! All very informative and most helpful.
For what it's worth, here's my application: I'm building a tool for image processing which needs some manual input in a few places (e.g. user draws a few lines). The images are greyscale images with 12-14 bits of dynamic range (from a microscope), so I need to have some basic brightness/contrast/gamma controls, as well as allowing basic drawing on the image to get the needed user input. It looks like GL or wx will be best suited here, I think? (I presume that python/numpy/ [GL|wx] can keep up with things like dragging a slider to change brightness/contrast/other LUT changes, as long as I code reasonably.)
Anyhow, thanks for all the input,

If you want to explore the array interactively, blink images, mess with colormaps using the mouse, rescale the image values, mark regions, add labels, look at dynamic plots of rows and columns, etc., get the ds9 image viewer and the xpa programs that come with it that allow it to communicate with other programs:
Then get the Python numdisplay package, which uses xpa. You have to get numdisplay from inside the stsci_python package:
Just grab the numdisplay directory from within that. Older versions of numdisplay are standalone but don't work perfectly. Beware, there are outdated web sites about numdisplay on the stsci site. Don't google!
Run ds9 before you load numdisplay. Then you can send your python arrays to a real interactive data viewer at will. There are even mechanisms to define physical coordinates mapped from the image coordinates.
