libglib2 = 2.32.4 (included with glib-2.0)
gtk+-3.0 = 3.4.4
glib-2.0 = 2.32.4
gio-2.0 = N/A (either unneeded in ArchLinux or included with glib-2.0)
libsoup-2.4 = 2.38.1
webkitgtk-3.0 = 1.8.3
Since I have no developer privileges, I am currently unable to ask the developer or maintainer of the libwebkit3 package to add the GtkLauncher program. I could try to find a version in the AUR to compile it myself and test it, but that would take some trial and error.
My current version of the packages are:
