Hi Ellie,
Well, my first thought was NO way. But in chatting with Betsy here at KAF and doing a little online research it seems like it could be possible. We would say that if you can, pick up an inexpensive hand mixer at the consignment shop. It will really help in making this icing.
Barring that, I did find a little advice here on Daring Kitchen. The advice of two whisks should help, in our view. Betsy also recommends very, very soft butter. In fact, you'll probably need to place the bowl in an ice bath every few minutes of whipping to get it to firm up. A large spatula for folding the icing over to cool it can be helpful too.
Best of luck with this, be sure to let us know how it goes. ~ MJ
