Adding second call to action button

Wanting to Add more than 1 call to action button! I posted an example above on kinda what I am thinking. They have 3 buttons that say Design/Marketing/ Web. Wanting to do something similar on my homepage. How should I go about it?
Downloading plugins like the header and footer script? If so after I download it, what code should I insert? And then next where do I go on my dashboard to locate the changes?

Sorry I know a lot of questions just trying to figure out Wordpress!

Anything is Helpful! Thank you!!
