There's already a lot of GUI built into every desktop. Have you looked at
them?

I keep hearing this "arcane" - even the author of xkcd commented about not
remembering tar flags... and yet, 80%-90% of them are trivially obvious to

firewalls, there's always copy an existing line and edit, then do a syntax
check.
