The Lua and physics engine is great for making games. I have to say it is the bomb!
I have noticed it is not as easy to make nice native looking forms with radio buttons, checkboxes, list, multiline textboxes and so on. Would it be easier to just use the your browser control pointing to a local html page for this? A lot of people already know html,css for making forms. Do you have an example of posting a form locally and sending it's info to a remote server with a response?
It seems like it would be reinventing the wheel trying to do forms with absolute positioned elements using Lua code.
Kind of like a hybrid of Corona and PhoneGap would be the perfect multi-platform solution.
