system-config-firewall is a python based Red Hat tool.
The best way to manage your firewall is by configuring iptables by hand. It gives you minimal rule sets which are clear and easy to read.
If you absolutely need a GUI, then try included debian tools such as gufw, firestarter etc. but note that they can only configure a small subset of what iptables are capable of. They also often given rule sets that can be difficult to read.
If you are coming to debian from rhel/fedora+clones and are missing some of the redhat tools, note that you are probably better of adapting the recommended work flow of the distro you are using.
Having said that, e.g. system-config-samba works fine on debian so far (but again, configuring samba by hand is not that difficult).
The real work was done by the person who did the patching (can't find a specific name -- just Ubuntu Contributions)
This was done on Debian Jessie. I may have missed some of the pre-requisite dependencies. Post comments and I shall add.
Anyway, look at this as an exercise, nothing more.

You can also use your pre- and hand-configured rule set and put it in /etc/default/iptables and /etc/default/ip6tables, then edit with system-config-firewall (for whatever reason).
