Is it possible to replace a debian ttyx console window with a graphical application?

On debian, how can I replace a ttyx console window with a graphical application? I am running debian 9.3(Stretch); it does not come with a graphical desktop as it's more of an Internet of Things version of debian. It comes with 6 ttyx consoles and I want to know whether or not one of these can be replaced with a graphical application. The reason I am trying to figure this out is to view network diagnostics for my server in real-time(I already made the graphical application). My application uses x windows as a graphical subsystem and my IoT server does have a graphical head.
