Build a wordpress website with a type form

I would like to create a beautiful wordpress web application with a typeform similar to this:
https://globalmobilityservices.pwc.com/

It should have the following pages:
1. a landing page,
2. input page where the user can select a territory/ country
3. summary for the country, which is the first 3 columns of the attached spreadsheet (with the option to choose additional details)
4. detailed page for the country which is the last 4 columns.

Please show me how to enhance and maintain the wordpress site in future.

Thanks
