Just make sure you use a bowl, and not a pot. You wouldn't want to be labeled, wait for it, "A POT-LICKER"!
And yes, whipping cream can be used to make a ganache. Chocolate has the required fat to thicken it. You may have to adjust the amount of chocolate to get the texture you want. And as has been said, unsalted butterfat can be added if required, to replace the amount of butterfat that differs between double cream and whipping cream.
