How to add “Stick this post to the front page” to front end?

I have a baseball related website with multiple authors. I use the “Stick this post to the front page” to denote an “Editor’s Pick” on an article. I would like to add a link/button to allow editor to do this from the front end. The method can either be in the article itself or in the Admin Bar. I do not really have a preference.

Add quicktag buttons to the HTML editor

I am trying to figure out how to modify the HTML editor in wordpress; on the image below you can see a screenshot of the editor and the buttons on the top. Is it possible to add new buttons? I would like to add a button that will insert “” tags and some custom short-code tags as well. I know it’s not impossible, but does anyone know how to do it?
