You could write this program in python rather easily. (if you use Eagle for the GUI, by far the easiest way of making a GUI on Maemo)

just a few buttons sending requests to a webserver, that isn't hard to do. (just a few lines of code, please look at basic urlib examples in python and search for Eagle and python for examples using the GUI toolkit)

The trouble is that is isn't "skinnable". It just looks like a normal Maemo application . Using PyGame you can make the GUI look like anything you want, but it is more difficult to program than eagle. (But I don't have much experience scripting Pygame)
