Help Needed Please!

I am new to Terminal and writing codes in general. I am trying to set up a quick program that would click a twitter link once tweeted and do a couple commands on the site once opened.

For example, Nike.com twitter tweets a link and the program will automatically click the link for the shoes and add it to your checkout cart for you to put your payment information in. Here is a YouTube video example: http://www.youtube.com/watch?v=yWIwUDF77SY&feature=youtu.be&t=2m5s

Is there anyone that can help me figure this process out? Any help would be greatly appreciated!
