Oh I didn't see the countertops mention I thought you meant just the cupboards.
No do not paint the countertops...bad juju. Paint will not work on countertops at all it will flake off with the use of knives or other objects on the countertop. The moisture used on and around the countertops will not help either.
Paint never truly solidifies so it is not adviseable on food prep surfaces at all.
