You're welcome, Sutee. I don't expect you to use the softwares themselves, instead I thought you would be able to draw some information from them. They are not my softwares so I can verify the claims either. I hope you get what you are looking for.
Some extra info: Firewall Builder is a Qt program that helps you write iptable/netfiler rules. As such it's only for Linux and MacOSX http://www.fwbuilder.org/
But I did some extra research and found an open source Firewall for Windows called Netdefender. This has a Port scanner to scan for open ports: http://www.programmerworld.net/personal/firewall.htm This one is in Visual C++.
Again same premise, draw from it what you can to get what you really want.
