Applying to Oxford can be a daunting prospect, but that should not put you off! Everybody is in the same boat, and there is no reason that you should not have a go yourself. 

All applications involve a completed UCAS form (including personal statement) and academic interview. Some might also involve written tests and submitted written work. Full information for the subject you are thinking of applying for can be found on the main Oxford website.
