There is a Python GPIO library in the package repository of Raspbian, but no C or any other counterpart at this time.
You can search for them yourself my typing:
$ apt-cache search gpio
If you understand how the GPIO works, you will notice that you can access the main functions using the file system mapping, just by reading and writing into files in the file system. This option is auto-updated together with the kernel and modules.
You can always use direct register access to use the GPIO, as described in the elinux RPi Low Level page, but I don't think that would help you achieve your objective though.
