Widgets are not plugins. They are whole objects. There is no extensible 
feature to them.

You will have two choices:

1. Copy an entire GTK widget and give it a unique name.
   Example: GtkButton becomes GtkMyButton

2. Create a shell widget that uses existing GTK widgets inside of it to 
do what you want. In the event you need to touch the GTK widgets inside, 
you can make your new widget a simple struct and have pointers to the 
interior GTK widgets.

I would suggest number 2, unless you are doing something very radical.
