Using WYSIWYG way you dont need to write any line of java code, the code will be generated for you by the designer. You can easily add any control on a composite by using drag-and-drop technology, add an event handler to your control, change various properties of control using property editor and much more. Generated code doesnt require any additional non-SWT library to compile and run: all of the generated code can be used without having the designer installed.
