take a look in the appletstrip containment in the plsma-mobile repo.
that doesn't do grouping, however it manages and positions applets in pure 
qml, needing access to only a couple of functions of Applet and Containment.

it puts all applets in its own item, called plasmoidcontainer, then the 
outside qml will be able to do anything it wants with it.

probably isn't still enough to do what do you want, but take a look and try to 
do a raw prototype of what do you need, so will be easy to figure out exactly 
what it's missing ("just" ways to easily save/restore the structure of the 
groups i guess?)
