Newbie Needs Help – Login -> Fill Form -> Submit -> Logout

Hello WP Community,
I am new at wordpress and have very little experience with code (I lie, I have no experience with writing code). I have built several websites using wordpress but am still a newbie so please excuse me if my question is unclear or simple.

I am working on setting up a website that is very basic. When the address is entered it will take the use automatically to a
1. LOGIN screen – here it will display NAME/PASSWORD/Forgot Password. Admin controls who can login.

Once they login it will automatically open up the main page (only page)
2. ONLINE FORM – here the employee will fill out a form which will have required fields. Once completed the will hit submit

3. SUBMIT – once they successfully submit the form the follow up screen will automatically logout the user. If there is an easier way to this i.e. give use option to go back to ONLINE FORM or LOGOUT, that is fine.

If I am missing any steps in designing the website your advice is greatly appreciated.

Thank you
