Basic Widgets

WordPress widgets are classes, which makes them easy to duplicate, even if you've never worked with object-oriented programming before. A class provides a blueprint for objects that will be reused in various ways. Creating a new widget is a matter of copying the basic widget class, then adjusting the enclosed functions to output the content you have in mind. The widget class contains four functions: one that registers the widget, one that prints the widget output, one that updates the widget options, and one that displays the options form.
