WordPress HELP!

Hello!
Thanks for taking the time to read this!
I am building a website with WordPress. And on my 'About us' menu. I have the perfect structure plan in which I want it to look like. I want it to be like a square note format with the text inside. I was wondering if there is a plugin I need to get to make it the way i want it.
Please help me out!
Thanks a lot! < heres the example I made on PhotoShop

Why dont you use a plugin with shortcodes etc ?

You can use Column Shortcodes plugin thats simple and easy to use

Jshortcodes will do this for you I believe, you need to set border radius to 0. http://www.jshortcodes.com/shortcodes/
Hope this helps.

thanks a lot!! much appreciated!
