Is there a plug in for this?

Ok so i am making a website and decided to make it into a couponing website and i have a theme called daily dish pro by Genesis, i made the following menu ( main page, store deals, coupons, etc…) so for example if i want to to post about store deals, i want the deal to be posted under that page as well as under the main page. My view for the main page is that it will hold all the recent posts from all the pages. How can i do this? I have been trying for 2 weeks and cant figure it out
