assuming you are doing all this code from within a DisplayObjectContainer or one of it's subclasses
you can add a property to the class say var lastTextField:TextField
and then override the addChild function
override public function addChild(child:DisplayObject):void
     if (child is TextField)
          lastTextField = child;
     super.addChild(child);
you will also need to add a function
private function removeLastTextField():void
     if (lastTextField != null)
          if (contains(lastTextField))
               removeChild(lastTextField);
          else
               trace("lastTextField has a different parent: " + lastTextField.parent);
          lastTextField = null;
     else
          trace("no textfield to remove");
you can then remove the last added TextField by calling
removeLastTextField();
if you want to be able to undo more than just the last one you would need to use an array of TextFields instead
