You could program something by using locator() perhaps although as 
Greg mentions
it isn't clear what you want.

Along those lines, in addition to the above mentioned packages, 
you might want to look at some packages that use cairoDevice 
to create interactive graphic displays. For example, you might 
find ready made features in playwith or you can use gWidgetsRGtk2 
to create something on your own.
