Start from reading "Programmable Completion" section in bash manual,
then proceed to `compgen' and `complete' builtin commands description.
If you plan to integrate your completion with bash-completion, then
there are plenty of example scripts for you to learn from in the
bash-completion distribution. If you don't want to depend on 
bash-completion, then I'd recommend to look into this completion:

 http://code.google.com/p/sbopkg/source/browse/trunk/src/usr/doc/contrib/sbopkg.bash

it's simple and quite clear.
