What is the quickest way to make a widget?

1. The Widgets API is the quickest way to make a widget that’s reusable. Example use:

   class My_Widget extends WP_Widget {
       /** 
         * PHP4 constructor
         */
       function My_Widget() {
           My_Widget::__construct();
       }
   
       /**
         * PHP5 constructor
         */
       function __construct() {
           // actual widget processes
       }
   
       /** 
         * Echo the settings update form
         *
         * @param array $instance Current settings
         */
       function form($instance) {
           // outputs the options form on admin
       }
   
       /** 
         * Update a particular instance
         *
         * @param array $new_instance New settings for this instance as input by the user via form()
         * @param array $old_instance Old settings for this instance
         * @return array Settings to save or bool (false) to cancel saving
         */
       function update($new_instance, $old_instance) {
           // processes widget options to be saved
       }
   
       /** 
         * Echo the widget content
         *
         * @param array $args Display arguments including before_title, after_title, before_widget, and after_widget
         * @param array $instance The settings for the particular instance of this widget
         */
       function widget($args, $instance) {
           // outputs the content of the widget
       }
   }
   register_widget('My_Widget');

2. If you don’t particularly care about having proper custom widget you can use a plugin like PHP Code Widget to run your code snippet
