Hi Tim… I am not aware of any framework…. And I would love to know also.
However, I did write up some information on how to create some virtual buttons on the screen to control the GPIO. This writes directly to the framebuffer, so no X is required;

I have been thinking of updating it for PiScreen and cleaning the code up a bit. I’m not sure if anyone would be interested.
Mark, I would be interested in using this. Probably in a slightly different way. Rather than controlling LED’s, it would be great if the buttons could be used to execute scripts. For example, I am using gphoto2 to copy photos off a SD card to a USB drive. I would like to trigger the script to copy photos by pressing a button, then return back to the buttons once executed. Also having a button to properly shutdown the pi would be useful.
Hi!
