Lightweight User Interface Toolkit (LWUIT) is a Widget toolkit developed by Sun Microsystems to enable easier Java ME user interface development for existing devices, including not only traditional Java ME environments like mobile phones, but also TVs and set top boxes with features like swing and recently javafx.
[1] LWUIT was created by Chen Fishbein of Sun Microsystems Israel development center (SIDC) who started developing LWUIT for an internal project.
[2] It has also been used a part of the Brazilian digital TV interactivity middleware, [Ginga] specifically in the Ginga-J technology.
[3] LWUIT is inspired by Swing and supports many of its features including pluggable look and feel, layout managers, etc.
However features such as MVC, layout managers, renders and the EDT are directly related to Swing.
