I have been tasked at making a couple of visual programs for simple data collection. I'm very proficient in Perl, but I don't often work with Perl in the GUI realm. I have played a bit with the widget toolkits wxWidgets and Tk in the distant past, but the nature of this task is less about the widgets and more about the mouse/image interaction.

The core idea of these programs is to show a large graphic, and to allow the user to place and move pushpins or other markers on that graphic. The back end would identify which logical area they touched, e.g., what voting pin they put on each state on a map.

While I understand a lot about scaling images, doing basic geometry for hit-testing, etc., what I don't know is the current state of toolkits or modules that exist to support much of this quickly. I just want to get this task out of my queue, not reinvent the world.
