For the last 5 years, I've been doing nothing but Java UI (Swing & SWT/JFace) development. Recently, I decided to get back into using C/C++, a skill that I had never fully developed. When I came across wxWidget's, I thought to myself, "Wow, this won't be so bad after all.", keeping in mind how spoiled Java has made me. I had no idea what kind of power and flexibility I was missing out on.
That toolkit alone was enough to push me over the edge, and wxAUI will definitely keep me from ever looking back. I only wish I had taken the time to learn 5 years ago, my UI's could've been so much sexier today.
Thanks for making this easy (well, for most people) and fun. I only hope I can get the jist of using these libraries quick enough to outshine my peers.
