I created the attached by these steps in 4.6.0 designer: 

- Create the dialog
- Drag a scroll area onto the dialog
- Set the dialog layout to vertical
- Drag a frame onto the scroll area widget
- Set the scroll area layout to vertical (which actually sets it on the
internal scroll area widget). 
- Dragged several buttons onto the frame
- Changed their minimum height to 100
- Set the frame layout to vertical

Voila! 

Hope that helps, 

Tony
