Assuming you come back and post again, please remember, that you're asking someone create something for free. This means someone has to be willing to do the work for free. From what I've read on these forums, everyone is working the computing field and are here in the forums because they're interested in the technology, but it's mostly related to their work. I don't think very many people are here "just for fun."
So member Oreeh is asking for more info as to why the other product doesn't meet your needs. You say you "must have a GUI." Well, we're sorry, the only currently available "free" product doesn't have a GUI. As the saying goes, "You get what you pay for." So this may mean that you'd have to hire someone to create the appliance for you. You do realize that many companies make "trouble ticket systems" and charge an arm and a leg and your first born child for it. So to even have one for free is amazing, in my opinion.
