I'm not sure what forum this fits into, if any, but the program itself is going to be written in Java (not that it matters much). My question is, what is the easiest software to use that I can create a drawing of a GUI with? The GUI I want to draw is going to have tabs, a scroll bar, a file menu, text fields, labels, and check boxes. I'm looking for something that can do this and make it look clean with very little learning curve. Has anyone used anything that fits this description?
