Give it a try. For GTK2 you can change a few things around to get it to work.
Pass the selection or chooser with your apply button "clicked" signal and you can apply the changes.
I tried the following with Ubuntu 16.04 and GTK2.24.30 and it worked. Maybe get a start at setting something up. I would recommend GTK3 over GTK2 but if GTK2 is the needed library then program with it.
I don't see a deprecated warning for gtk_font_selection_set_font_name() when I compile in GTK2.
