You're likely to get some small berries your first summer (or spring, depending on the variety). Some people tend to pinch off the flowers the first year so the plant can expend its energy growing deep, strong roots. The stronger the roots the more likely your plant is to survive through its dormancy in the winter. Some people say it doesn't matter. Either way the second years' harvest will generally be larger than the first years'.
If you are going to spend your money consider buying dormant strawberry roots. They are usually one year old already, so you put them in the ground after the last frost and they will be quite productive once they come up. You can buy a bag of ten dormant roots (usually guaranteed to grow) for $3.49, American.
There are June and everbearing berries. For some great, detailed information and instruction check out some of these threads or head to the fruit forum. Good stuff there!
