What I did was:
   - Connect to size-request for the label and return a small width
   - Connect to size-allocate for the labels parent container with the
     connect_after flag/api
   - In the size allocate, allocate the right amount of space for the label
     (usually thats just allocation.width - border_width * 2)

This little trick gives you wrappy and growy labels.
