A kumquat experiment

Citrus can only grow in pots in my area, they may be hot in our warmer seasons but will have to sleep inside  on cold nights and winter inside.  A friend gave me a couple of kumquat fruit, which I love, and harvested the seeds.  I removed the outer protections (I'm sure it horrifies some readers that I don't know the technical term...the crusk?-I made that up) and put the naked seeds in a cup of water in a window, will they germinate?  Will they ever produce fruit?  Any advice on how to proceed?

Thanks to all!
