Interactive Workflow Tool [migrated]

I’m interested in making an interactive work-flow tool like the one on this New York Times (NYT) website.

The members of my team would click on Yes or No buttons on the work-flow tool, and it would show interactive messages similar to pressing the buttons on the NYT website. I have heard of online tools like Survey Monkey but they can't accomplish this kind of interactivity. I am not a web designer and I don’t know the coding to do this, so I want to use an online platform/tool to do this. Can anyone recommend an online platform or tool that is simple to use and can create such a workflow?
