I agree completely. This patch accomplishes nothing, really, except to 
separate the changes needed to set up for having a better gui.tcl from the 
new one when it comes. As such I was trying to keep the list of changes to a 
minimum. The changes included here are just enough to clean up the calling 
convention and add the guisection attribute which my plans for gui.tcl hinge 
on. Anyway, I just copied the program logic straight across between languages 
to have a nice clear and understandable commit.

I am working quite a bit on gui.tcl, which has a rather low cost of modifying. 
Right now I've got notification in the output screen with icons when the 
program starts and finishes running and display and update of the command to 
be run while the options are edited. I'm playing with balloon help, separate 
tabs for options and output, contemplating a help tab to go along with them, 
and am somewhere in the midst of writing my first experimental layout rule.
