silly display programming question

[pixel fairy]

ive been using opengl for most graphics stuff, but now i want to write a
simple app (gui for scarse, a scanner calibrater) and i think opengl is
overkill here.

whats the simplest method of displaying an image with some interface
elements over it, in this case a loaded tiff (probably using tifflib)
with lines (of inverse color perhaps) that can be moved.
