you might be able to use gtk_show_uri (or one of the functions it replaces) to do this,
http://library.gnome.org/devel/gtk/stable/gtk-Filesystem-utilities.html#gtk-show-uri
it's a new function in GTK 2.14, so it may not be available to you yet.
Also, I haven't been able to get it to work in windows properly, but I'm still looking into it.
Here's what I'm working with:
