How to create an unauthenticated frontend mobile create-only form

I am new to CUBA-platform and am trying to see if I can use it in an upcoming project. Its a simple Application for Employment application, thus the frontend user interface needs to be mobile based and have an unauthenticated create form. A plus would be to have a re-captcha function as well. I’ve searched through the documentation and examples, but have not found a suitable answer to these questions. Any help would be appreciated.
