Use the usual GTK+ widget placement methods - create a gtk.Window, add a
VBox/HBox/Table etc and place the figure widget and other widgets in the
container. This would be using the matplotlib OO interface like in
examples/embedding_in_gtk2.py

Should matplotlib have turned itself into a widget library / GUI toolkit?
I know that for a long time John resisted the temptation to add widgets
to matplotlib and wanted matplotlib to focus on being a plotting
library. I agree with this view and think the danger now is that
matplotlib will become too big and bloated and harder to install (like
the old SciPy?).

I would prefer to see a 'matplotlib-core' which is a minimal module that
focuses purely on plotting graphs. Other optional modules (like
'matplotlib-toolkits', 'matplotlib-widgets', etc) could then extend
'matplotlib-core' by providing extra features.
