Build bot to click links and play songs using proxies

I need to develop some software for me. I would like this software to be developed for Mac but will entertain a PC application for a considerable price cut. I want a program that will use proxies to go to a link, then bounce from that link to another link. Then when on that link, I want it to click play on a music player (most likely sound cloud) and then repeat using a new proxy. I want it to be able to run without using macros in Firefox, chrome, etc. I can do that. I also want it to randomize the times so to make the traffic seem real. I may also need software to sign up for accounts on a website and then verify the email the website sends out. Then clicks a button to like a post on the original website to upvote the post in order to create popularity and start a buzz on the site.
