Google app suite question

[1]

Does anyone know if there is a way to integrate Google Sheets, Google Docs, and Google Calendar into a web page interface? If you click a link, an input box pops up wanting a number. Could I then have that number inserted into a Google Sheets project? 

Thought process here. 

I create QR codes and paste them around town as a social experiment. When someone finds it and scans it with their phone, it will take them to a link that explains the experiment. Then a box would open and ask them to input a number that they think is significant to them in any shape or form. Then they would enter a number, and that number would then be put into a new cell on an already configured Google Sheets project. Once the number gets entered, then it automatically gets charted in a pie chart, showing how often people picked a number, etc. All broken down in a few different categories.

I am really new at everything, but to me it seems like it could be done very easily. I just do not know where to begin looking, other than Google, and that is how I ended up here.

Thanks so much if anyone could let me know if this is possible or not.
