QUESTION Building a form + export data

[colorfill]

Hi!

I'm quite new to the world of getsimple CMS. What I need to do is to create a tiny, 3 max pages website. In one of them there should be a form with following fields:
- name,
- surname,
- email,
- contest answer
- data processing checkbox

how can I create it? One thing is important - i need a possibility of exporing all inputs to an excel file (xls would be great). Any ideas?

thanks!
