This has been done before, and probably many times. The last time I did that for a customer I ended up with a 7.5 kB / 111 lines shell script. OK, I did not have to support a multi-language interface, and it was all text based, but it included pretty good error handling and all the logic even to test for a specific dongle to be installed to enable the update. [And yes, it revealed a number of hush bugs, too. :-( ] I do not relly see why we need a graphics library with all bells and whistles up to and including support for TTF here... If you need a fancy GUI, please use an OS.
