Just use dpkg-deb --build
fakeroot #you need to pretend to be root to get file permissions correct
mkdir somedir #this directory contains your filesystem tree
mkdir somedir/usr/bin -p #stuff here will be in /usr/bin when installed
... #do whatever it takes to make this directory
mkdir somedir/DEBIAN #this contains package meta-information
vi somedir/DEBIAN/control #this is the debian control file. you won't be
#able to use shlibs to automatically compute dependancies
dpkg-deb --build somedir #this is approximately equal to those archive
#commands you want

It is, but for redhat you'd have to write foo.spec first.
For Debian, you have to populate the debian directory first.
