GUI toolkit for C... which one?
What is the easiest GUI toolkit for C programming? I've written a large amount of code for Linux that I need to add a GUI.
I looked downloaded GTK but it looks like a steep learning curve. I've heard about QT but their website indicate liscensing fees. wxWidgets looks simple with good tutorials but apparently is for C++ which would be another learning curve.
I'm serious about learning one of these but I can already see it will be a large investment of time. So which way should I go?
Same question for Windows
I'm writing a C application, initially on WinXP, but likely will be moved to some flavor of Linux. It's written in C because it needs to be very fast - the application could take months to run. I'd like an elementary GUI for Windows to create how-goes-it information that is more elegent than a DOS window. I have Visual Studio 2005 (novice) but am afraid of all the other stuff that might get dragged into the code if I use their GUI capability.
