Connect the backend with frontend

[subhojit777]

Found that the existing frontend https://github.com/subhojit777/questionnaire cannot be used, as it is very tightly coupled with deployd. Example, the UI participant.jsx used deployd framework for fetching the options.

Therefore, the frontend needs to be written from scratch. Refer the following for writing the frontend:
