osc-tui costume-rule-like

I mean, a good gui, is a gui that enable me to configure my openarena server, with the good ports open, and stuff.
Maybe, I could add python scripting support. 
How much a bad idea can this be ?

NOTE: this feature must be implemented at fist as optional, and maybe not package by default.
