I'll be the first to admit I am a terrible GUI programmer. I got turned off by GUI development because of how tedious Win32 programming in C used to be, and I never got too absorbed in GUIs because I found writing them to be overly tedious and boring. That having been said, I'd like to render level-2 data sort of like how retail vendors do it, but with a homebrew solution so I can annotate and put various markers into my depth book. Some questions: 1) Is there open source stuff I can lift for this and modify, because I'm lazy? 2) I'm looking at wxWidgets and wxPython. Does anyone have any other suggestions? Note: - Don't give a !@#% about speed - Just need it to look reasonable, does not have to be commercial quality Leaning towards wxPython, unless someone here hooks me up with something more deluxe.
