I dont know about seeds, but I bought some small plants years ago. When I say small, they were probably 20cm in height. They grew ok inside, once they seemed to have found their feet and were going well I transferred them outside...........didnt make it through winter, even though they were covered.
I would expect that even if you managed to get a tree to fully mature and produce cherries I wouldnt think they would be any good in our climate. Might make a nice talking point though.
