What do you mean by "window" ?

If you are talking about the toplevel window of your application, this
is technically not your decision to make - the window manager will
make the choice for you and activate/focus your application window
when the window manager decides it's a good idea.

You can on the other hand use gtk_widget_grab_focus() to set the
"focus widget" of your toplevel application window (for instance
perhaps the GtkWidget which has a GL enabled GdkWindow ?). This
will not cause your toplevel window to obtain focus, but should
ensure that the widget you chose has focus as soon as a user
enters your application.
