In grass 6.x, it was possible to set the active display by d.mon But in
grass 7.0 this has been removed. Therefore, d.where sits there without
outputing x and y.

There's no such thing as a "monitor" in 7.0. The various display
drivers simply generate graphical output; they don't have any
interactive functionality.
The version of d.where in 7.0 requires coordinates to be passed via
the coordinates= option.
If you want GUI functionality, you need to either write your own GUI
or extend the functionality of the wx GUI.
