Hi Patrick, I don't have an answer for you. But thought it might be worth to have a look at this: http://www.r-bloggers.com/getting-data-from-an-image-introductory-post/
Also, there was someone who presented a really simple GUI system in useR2010. Where his code gave a GUI based on R base graphics, where it added buttons above an image, and allowed to act on the buttons to induce an action. I wasn't able to find his talk on the website, but it exists and might help you with some of the coding. Lastly I would add that I would be curious to see how you would solve your issue. If you happen to solve it by yourself, please consider posting it back here.
