Thank you, I got it partially how I want it.

The button is sitting neatly on top of the playing area now, but it has 
a small grey box around it. See the screenshot at [1]. I think that the 
1 pixel grey border is added by an invisible container widget that holds 
the button in question somehow. I have set all the border values on the 
button to 0 already, so I think it's not the button itself.

Is it possible to remove that container, or set it's grey background to 
transparent so that the rounded button shape is drawn directly on the 
green canvas? A GIMPed mockup of the desired result is at [2].

It's no problem if it can't be done in Glade directly. I can simply load 
the glade XML file in C and execute a couple additional GTK commands on 
the button or it's container.

Thanks again!
