I ended up using AmiDevCpp, and that worked pretty well. I'd compile on my XP/Cygwin box, and tested with my A1200 UAE "box". Made a couple little things, but then ran out of ideas. So much has already been done. I also grew frustrated at the lack of active GUI toolkits that would allow for rapid application design. Designing the GUI from code, brought back too many painful memories. Thanks all for the comments I found them very helpful.
