Looking for a columns/layout plugin

Hi guys,

I’m looking for a plugin that would allow me to put my content, in the admin WYSIWYG, in two columns, as it will be displayed on my website.
On both columns I would like to put either text, image or nothing.

Here’s how I want to display the content on my frontend… and so in my backend as well.

I searched for it all day long and didn’t find anything interesting…

Thank you!
