If Gtk+ is built with support for both X11 and Wayland, you can detect it because an environment variable will be set.
A quick search (gtk3 wayland env variable) got me this: "When both Wayland and X backends are enabled, GTK+ will default to the X11 backend, but this can be overridden by modifying an environment variable: GDK_BACKEND=wayland." (https://wiki.archlinux.org/index.php/wayland) I suspect if Gtk+ is built without support for X11, that this may not work. A better option may be to look at https://developer.gnome.org/gdk3/stable/gdk3-Wayland-Interaction.html and make vapi bindings for gdkwayland.h.
