General :: Script To Automatically Saving Gnome Customization?

I was wondering if there was a way to create a script to automatically restore, on a fresh linux (with GNOME desktop manager) install, all my interface preferences. Let me explain; every time I install ubuntu (or any other distro), I find myself doing the same actions over and over again: delete the bottom panel, place the top panel on the bottom, put the workspace switcher in the bottom panel, add a shortcut to gedit on the bottom panel next the firefox icon, set 'oblivion' theme to gedit, and so on. Frankly, this is getting annoying.

So I was wondering if I could do it once and for all, and keep track of it on a script, that way on future fresh installs I will need only run the script and my distro will look the way I want it to. Before anyone suggests me to, let me point out I already tried replacing the newly-created ~/.gconf and the ~/.gconfd with the ones from previous "customized" distros but it gave me major issues in terms of window compositing, so I had to revert to the backed up gconf and gconfd directories.
