Okay, I know I have asked similar questions, but:
What is the easiest programming language to learn, that is still functional and easy to use on all operating systems, but similar to QBASIC, but can also create graphical interface programs?
(Need to be usable on operating systems besides Windows would be nice, but not necessary)
Something where I could, if I really wanted to, create a restaurant table management system
EDIT: A good guide or book that you know of for the language would be nice to know as well
