fruit trees from seed?

is it possible to grow fruit trees from seeds in the fruit we eat? i have just had a peach with my lunch and it just got me thinking as to whether i could grow trees from the stones.

if so how many years before they would produce fruit?

I grew a peach tree from a peach stone,but when we moved it was still only 5 years old, so we hadn't had much fruit from it, and I started to grow apples from seed in y office once, but they died!!  

bought some mangoes from asda, kept one a little too long and when we cut it open the stone in the midddle had split and there was the biggest seed I have ever seen, anyway we planted it and it is now about 8'' high with 6 leaves but we are not sure what we will get, does anyone think we will ever get fruit, tried to find info about it on the web but came up with zilch, any idea's.

I tried growing peaches from stones, but nothing happened. Then googled it and found I should have prepared them in various ways, from memory one way was to scratch them, and one way was to either put them in the fridge or the airing cupboard. Sorry to be so vague, but try googling and the info will pop up!!!

my apricot stone germinated and is growing nicely... infact i should probably think about re potting him into something bigger by now....

i'm thinking of planting some of tonights rice in our garden!!  The downstairs loo is no longer working, hoping the upstairs keeps going, got a child needs a bowel washout tonight, nasty thought if the loos back up!!

... correct rootstock for what you are growing and how  much space you have

RR has hit the nail on the head.  You will usually get a plant of some kind from a saved seed but it is likely to mature into a tree with entirely acceptable attributes (size, vigour, productivity, etc)
