erm...
???

Just create a profile file under /home/user/.kernel with all your settings and call it within DECW like
sudo kernel-config load myProfile?

With either sudser (not recommended) for resolving the password issue or an entry in /etc/sudoers.d/.

That were only pointers. If you need the whole solution (no spoon-feeding ) ask once more.

And to extend your use case: there is also a solution to have this done automatically with dbus-scripts.
