This kind of thing is called an "IDL program", and
people who use IDL get used to writing them. You can find
examples of how it is done, but basically, you have
to write a "widget" program (using IDL widgets) and
you have to respond appropriately to widget "events".
Here are some example programs that you can adapt for
your purposes:

You can also get a great deal of this functionality just
by putting your image into the appropriate iTool:
iImage, image

I'm afraid you will have to resolve it yourself by writing
a widget program to display your image. You might try this one:
