Create a Chrome Extension

Hi, I need a very simple Google Chrome extension It will contain: 1. A textbox and a button - When the button is clicked the browser goes to the URL that the user has typed in the textbox. 2. A textbox and a button - When the button is clicked the extension changes the value of a hardcoded cookie to be the value that was written in the textbox. 3. A textbox and a button - When the button is clicked the browser goes to the URL that the user has typed in the textbox. You can view the source code of an extension called EditThisCookie. It is much more advanced than I need, but I am sure you can find the part that writes to the cookie for reuse.
