as far as I know nobody is working on a GUI for packaging (like a IDE
but for packaging). If someone is please let me know, because I want to
develop something in this area for Debian and than I would like to help.
If not I may start something as long as there are no objections. The
main idea is to put the Debian policy into a interactive wizard that
helps building basic packages with normal Debian quality. No command and
only valid selection etc... like lintian at configuration time and not
just after- a guide that walks you through only lets you enter valid things.
