If the liblinear developers (or anyone) is interested in writing such an 
interface, I would gladly help them.  I suspect it would have to be done
as a completely separate exercise to the GLM command.

Have you some ideas how such an interface should work?  To what kind of users
do you think this would be of interest?  What level of expertise would they
