Need to make simple web app

simple web app that generates PDF charts.

1. The front end will look like the Goal Sheet Form.pdf
2. When the user clicks the button at the end a PDF is generated and that looks like Goal Sheet Sample.pdf
3. When the blue question mark is clicked a popup displays a paragraph of text which I will provide.
4. The numbers from the form will generate the number of circles and squares in the PDF
5. The data from the form should be outputted to a spreadsheet. A Google Sheets document would be best if possible.
6. I would like the web app installed onto a Weebly website.
