Easy newbi questions

Hi All,
    I am running RedHat Linux 8.0

    I have a couple of books on Gnome programming, GTK+/GNOME 
Programming by Peter Wright
    and GTK+/Gnome Application Development by Havoc Pennington.

    I have written an application, which all work fine, but now I want 
more.....

    So I have a couple of questions:


    1. How do I compile an application for the Gnome 2 libraries.

    gnome-config seems only to return information for gnome-1.0, eg.

> $ gnome-config --cflags gnomeui
> -I/usr/include/gnome-1.0 -DNEED_GNOMESUPPORT_H 
> -I/usr/lib/gnome-libs/include -I/usr/include/gtk-1.2 
> -I/usr/include/glib-1.2 -I/usr/lib/glib/include -I/usr/X11R6/include


    2. Where is there any documentation on Gnome 2 library use?

    Containing details on New Widgets and any that have changed.


    3. How do I write a panel applet for Gnome 2?

    is there a document, or a simple example peice of code.

Many thanks,
    Gary.
