Check out "Programs for Digital Signal Processing" by the IEEE press at your
university library.  It contains some of the classical methods (and FORTRAN 
source code) for designing FIR filters.

Another source for designing FIR filters is the classic "Digital Signal
Processing" by Oppenheim and Schafer.

A more current source is "Digital Filter Design" by Parks and Burrus.  The 
appendix contains FORTRAN source code for a couple of FIR filter designs.

But the easiest method to generate FIR filters is to use a commercial package.
MATLAB with the signal processing toolbook is a good one that comes to mind
(but certainly not the only one!).
