Dear Michael!

Of course this is possible - tghere are all sorts of kinases for sale. They 
only require the right sequence surrounding (consensus sequence) for specific 
phosphorylation. There once was a "Methods in enzymology" double volume 
(200/201) dealing with protein phosphorylation, but there is lots of other 
sources with protocols around.

Good luck!
