You can use a parallel port if you have one.

Basically the only way to do it directly is with the parallel port as armando said. However, it isn't the easiest thing to do.

Alternatively you could get a USB servo controller:

One of the data pins would be the obvious choice, as they are outputs.
But controlling it from Windows will be tough, as you only work with a "Virtual Machine" i.e. timing will be off, so better use DOS or Linux.
