How do I code a theme like this?

I’ve come up with an idea for a website that requires 2 blog feeds to be posted side by side on the same homepage. Kind of like http://www.rin-wendy.com/

I’m quite adept at coding “regular” themes, but having 2 feeds is totally new to me.

Would it require 2 different loops?

Any help would be greatly appreciated.

Thanks in advance
