Shells have a variety of tasks, but their main purpose is to interface for
users. Shell scripts are used for small, common-type tasks, but for
anything extensive I would use perl or C, because there is no real
enhancement for shells as far as programming goes, that's why most people
choose c/c++ because of the speed and optimization. Actually I use perl
over shell-scripts most of the time because of it's speed and routines
built into the language. Shells aren't used for graphics. Look into
tcl-tk or perl-tk and the X11 libraries for help with that.
