Well this is quite a simple task and the app will be made within hours. Let us know whether you want the three buttons mentioned, made available as in google chrome app, (it come out when you click on the settings section), or displayed at the bottom or top of the page displaying your website.
And to make it more interactive, we can also give small animation to give a small pop-up effect to the icon bar.
Will be looking up for your acceptance.
