A DrawingArea isn't a container, so not really (at the moment at
least). However, if you take a dip and learn how to write a container
in GTK (it's not really that difficult, though it requires to learn
how the widget system works), it's possible to write a canvas widget
that contains the other widgets...

...though to get this far you'll either have to do uglish things to
acquire the widget's drawing or wait for the offscreen rendering patch
to be in a GTK+ release to do it properly. And even after that, you'll
get the input problem, ie. you need to transform also the input events
(mouse clicks etc) for the widgets...

Hope: yes, practical implementation: at least not yet, unfortunately.
