Why don't you use a development kit instead? Designing a fpga board when you are a beginner isn't an easy task.

I fail to see what you want to do with the FPGA... If you just need to input/output some signals, a simple circuit with buffers connected to a parallel port, or a ftdi usb module (http://www.ftdichip.com/products/evaluationkits/dipmodules.htm)should be more than enough.
