Where can i get an auto clicking program that does the following?

I want an auto clicking program that will click at least two buttons simultaneously. The program may not exists (which i have a little doubt of ) but if so i am prepared to code it myself. I require the program to click on a button in a browser and then reload the page and then the button again then reload the page again and so forth. So if there is such may i please have a link or guidelines if i have to code it myself. Thanks
