Is there any tool which can help me build J2ME applications in short time?

I dont k开发者_如何学Gonow J2ME in detail it would be good if by using this tool I can design GUI and can create application in very short time.

Lot of frameworks available for j2me developing. I suggest LWUIT is best for developing UI and use the Resource Editor for design the UI. If You need LWUIT latest source code checkout here and build it. or they officially released LWUIT 1.4. Some example application available in LWUIT repository and even LWUIT 1.4 package.
