I want administrators be able to create events with some options, in my case (again talking about shooting matches) an administrator must select which disciplines (Air Pistol, Air Rifle, Small Caliber Carbine, etc.) are available for a match. This can be done with checkboxes.

Later on people can signup for an event and they must also choose an option (i.e. which discipline they want to shoot in), by means of a radio button. The possible list of options must be limited by the event the user wants to sign-up for.

Could this be done easily in CCK Signup?
