Code to do a completely external actionscript 3 file?

Question

If it's not too much trouble, could somebody post an actionscript .as file that would draw a rectangle on the flash stage, with the ONLY thing in Flash being the property assignment that you have to do.
I'm really new to this, and I have not been able to find any tutorials on this topic (other than someone telling me that the tutorials are out there).  I want to start hacking around with Actionscript and Flash, but I'm really frustrated because I can't get started.
I DON"T want to put code in the timeline, use code snippets, or use the actions window.
References to specific tutorials would be really appreciated.
Thanks!

Here is a class that draws rectangle:
package
     import flash.display.Graphics;
     import flash.display.Shape;
     import flash.display.Sprite;
     import flash.events.Event;
     public class ObjectWithRectangle extends Sprite
          public var fillColor:uint = 0xff0000;
          public var strokeColor:uint = 0x00ff00;
          public var rWidth:Number = 100;
          public var rHeight:Number = 100;
          public function ObjectWithRectangle()
               if (stage) init();
               else addEventListener(Event.ADDED_TO_STAGE, init);
          private function init(e:Event = null):void
               removeEventListener(Event.ADDED_TO_STAGE, init);
               var rectangle:Shape = new Shape();
               var g:Graphics = rectangle.graphics;
               g.lineStyle(1, strokeColor);
               g.beginFill(fillColor);
               g.drawRect(0, 0, rWidth, rHeight);
               g.endFill();
               addChild(rectangle);
Here is a class that implements the above class - if you make it a document class is Flash IDE - it will show a rectangle with random colors:
package
     import flash.display.Sprite;
     import flash.events.Event;
     public class DocClass extends Sprite
          public function DocClass()
               if (stage) init();
               else addEventListener(Event.ADDED_TO_STAGE, init);
          private function init(e:Event = null):void
               removeEventListener(Event.ADDED_TO_STAGE, init);
               var rect:ObjectWithRectangle = new ObjectWithRectangle();
               rect.fillColor = 0xffffff * Math.random();
               rect.strokeColor = 0xffffff * Math.random();
               rect.rWidth = 200;
               rect.rHeight = 250;
               addChild(rect);
