Do you have MyWindow in your .ui file?

I do this quite extensively in my application, here is one example:
http://git.xmms.se/xmms2/abraca/tree/src/components/server/server_browser.vala#n42

and the .ui-file:
http://git.xmms.se/xmms2/abraca/tree/data/ui/server_browser.xml#n18

it was a while since I wrote that and I'm not sure if you need to
explicitly add the Buildable interface or if that comes with the
widget you inherit.. but anyway.. something like that ought to get you
started.
