I am researching prototyping tools for mobile games that are developed in J2ME and Brew. I need to create rapid prototypes of interfaces relatively quickly and be able to port something to a mass market phone for a usability test or a marketing demo.
I need something that 1) has a low learning curve, 2) is easy to port to a mass market phone and 3) utilizes a WYSIWYG interfaces without a lot of coding.
I'm not finding a lot. WAP isn't going to do it for me and Flash Lite seems like its available on a limited number of handsets, which tend also to be smartphones.
