Email me directly offlist and I can give you some help with this if you are really committed to doing it this way.

It also depends on how 'electronics minded you are, though. . .

I looked at the same thing a few years ago and ended up buying a 
dedicated clock unit that was designed to trigger bells. It seemed a lot 
simpler than something I put together that involved running a computer.

Here is one example of several that American Time and Signal sells: 
And here another from Lathem Time: http://www.lathem.com/sona.shtml 

When I did this, I was able to find a unit on ebay for a reasonable price.

Good Luck!
