Yeah, I could probably put together a GUI for the programs... the real meat of the app is in the expression parser library anyway, so it shouldn't take long to make a GUI for the templatizer, at least... I personally don't see much point in making a GUI for the calculator part, because that would have to be changed every time I added a function or operator, and it would be *quite* cluttered with all the functions I've added - unless all you want is a text box where you type in equations, but then how's that better than a command line anyway?
Of course, when you say a GUI for the templatizer, do you just mean something where you can select an input text file and select an output text file and hit "generate"? Or do you want to be able to fully configure the various data files in the GUI? I think there's a PropertyList control which might be of some use, if I can figure out how to manipulate it to add and remove abilities, tech reqs, etc. the way I want...
Oh, and BTW, there's another bugfix release out now - was having some more problems with parentheses, those pesky things
