Plugin or project to generate survey

Hello,

I’m looking into building a tool on my website that will give my users
the ability to generate survey and then look at results.

After looking into it, it seemed to be significant amount of work! I was
wondering if there is similar tool/plugin that I start off.

I found this: Index of / which seemed a good
start but I was wondering if you know of other ones.

Cheers,

Tam
