Can there forms be used to handle events?

I'm curious if your forms could be used to handle event sign-ups. 

Thank you.

You can check out these sample event registration form templates:

Please review and let us know if this would suit your requirement. 

Else custom forms can also be created. If so, please let us know how the sign up form needs to be created?
