I don't know how to configure xdg-desktop-portal-gtk to open a link with a specific program.

It doesn't use xdg-open. I'm confused.

Yes, you are indeed confused: this is the issue tracker for the GTK implementation of the xdg-desktop-portal interfaces.

If you have questions about how to use the portals API, feel free to open a topic on the xdg-desktop-portal discussions.

If you are using a toolkit, it's likely you already have portal-aware API.

I think the answer you are looking for is the MIME Apps Specification: https://specifications.freedesktop.org/mime-apps-spec/latest/

It doesn't use xdg-open.

Correct. It uses code from GLib/GTK that implements the freedesktop.org MIME Apps Specification, linked above.

The xdg-open(1) tool has various desktop-environment-specific code paths, some of which use the MIME Apps Specification and some of which use legacy desktop-specific mechanisms.
