Building User Interfaces
GWT user interface classes are similar to those in existing UI frameworks
such as
Swing and
SWT except that
the widgets are rendered using dynamically-created HTML rather than
pixel-oriented graphics.
While it is possible to manipulate the browser's DOM directly using the
DOM interface, it is far easier to use
classes from the Widget hierarchy.
You should rarely, if ever, need to access the DOM directly. Using widgets
makes it much easier to quickly build interfaces that will work correctly
on all browsers.
