Actually, if you want to get technical, yes you can spread it by kissing and shaking hands (not hugging though, because there doesn't have to be skin to skin contact for that). Since HPV includes the strains that also cause regular body warts, including plantars and palmars warts, how do you think little kids get warts on their hands? Certainly not from having sex. They pick it up from touching other kids.
So it stands to reason that simply shaking hands can do it. But if you're only talking about genital warts or the cervical cell changing kinds, you'd have to wonder where their hands have been and where you put your hands. As for kissing, why not? People can carry the virus in their mouths (oral sex) and do get mouth and throat cancer (very rarely but it does happen).
