If the GUI is just a wrapper, then that's true. If the GUI is part of the
program, then it should prevent certain combinations of input, provide
warnings, and otherwise behave as an integral part of GnuPG. That is not
nearly so simple. Designing wizards to ask the right questions and process
input is tedious, and often complicated.

Tcl/Tk and java make usable cross platform GUIs. There is at least one
person who is willing to work on this kind of project, but it's not me. I
have built just enough end user apps to know very well that there is a
significant PITA factor in designing apps that must reliably process input
from potentially clueless users.

It wasn't a matter of answering a question. The application code was
updated to add a feature in response to a post on this list. The interface
change was a relatively simple matter of allowing another command line
option. Fitting those same options into a GUI is not necessarily so
simple.
