It's possible, but it's painful.

You need to create dummy nodes where you have children, and fill them in
when the node is expanded.  gmc (GNOME's filemanager) indeed does this
in gtkdtree.c.  gmc is available in the mc package from cvs or
ftp://ftp.gnome.org/.

GTK+ 2.0 will have a much better way of solving this problem.
