I have uploaded a simple gui, which you can use to generate images via satpy.:
satpy_selector.py
See:

http://www.alblas.demon.nl/wsat/software/satpy.html#gui

In the script you need to add locations for the satellite data. With an option one of the locations is chosen and the available data is presented. Select an item, an area and (for polar sats) day or night and the image will be generated.

This is a first trial; at least a composite choice has to be added (which is satellite dependent). Currently only tested on Linux, but should work for Windows too.

Note that this gui cannot be used with the original scripts because these have built-in locations for the sat data (no option available), which would mean the need of an exact copy of these built-in locations in the gui script.

Cheers,
Rob.
