You can use weston-keyboard with GTK3 on Weston if you install an appropriate IM
module for GTK3 that support text-input-v1 protocol of Wayland.

We are developing such module:

   https://gitlab.com/clear-code/gtk-wayland-textinputv1

We have also a yocto recipe for it:

https://gitlab.com/clear-code/meta-inputmethod/-/tree/master/recipes-gnome/gtk-wayland-textinputv1

Although it's not support scarthgap yet, not so difficult to port.

Even if you finally success to build it, probably you can not use it on your system.
It requires some wayland protocols that aren't supported by Weston:

We are also developing a virtual keyboad software for Wayland (mainly for Weston):

Unfortunately we don't publish the yocto recipe for it in some reason.
But creating it based on above meta-inputmethod layer isn't so difficult.
