Post links to Social Networking Sites directly from website's admin panel

I've developed an e-commerce website in php. There is an admin panel with all product list and respective links on website.

I want to put options to share the product's link on various social networking websites.

facebook, twitter, linkedin, google+, for example.

A separate button for each website would be put along with product name. Is there any solution to post product's links directly from website's admin panel ?
