And an exaggerated concept of what a 3x4 widget with multiple buttons inside might look like: http://dl.dropbox.com/u/30586759/multiple%20buttons%20within%203x4%20widget.png
I have no idea if the android widget platform actually allows this kind of thing.
This is doable, and I see that might work on a tablet. However it is not a priority for me I want to keep this as simple as possible for the moment.
PS! if you want to try your self feel free. Android is Java and all the layout is done in xml
