You would want to implement any such restrictions within the remote desktop
server itself. Attempting to enforce such restrictions on the client side
(within Guacamole) would likely prove infeasible / too easy for a user to
get around.

Keep in mind that, from the perspective of Guacamole or any other remote
desktop client, the close button is no different than anything else on the
screen; it's an image. Once the incremental changes describing the contents
of the screen are received by Guacamole, all semantic details of that data
is absent. Only the remote desktop itself is aware of the fact that a
particular application has buttons of any kind, whether it should open that
application automatically, etc.

In the case of RDP, there is native support for opening applications upon
connection, but preventing the user from closing that application would
need to be configured within the OS or the application in question. RDP and
the RDP client will not be able to prevent this.

For VNC and Linux, the VNC server operates as an X11 server, and there is
no need for you to run a full desktop environment. If you restrict the
server to just the application you want and some window manager, then that
would be a start, but again you'll need to implement any further
restrictions within the OS or the application.

It's not advisable, since any such restrictions would be trivial to
circumvent. You wouldn't want to restrict the ability to close an
application or open other applications purely through preventing (for
example) mouse clicks to certain locations; you'd want to have the
application itself refuse to cooperate, and the environment around the
application refuse to do anything but run that application.
