Can CellWidgets contain custom composite widgets ?

Can I create custom composite widgets ( panels containing label, button, edit box),
and include these custom widgets within the CellWidgets (CellTable, CellTree) ?

for example, when clicking on a node, instead of displaying just a text,
be able to display a composite widget,
or including drop-down panels (similar to disclosure panel) in the CellTable rows.
example: http://code.google.com/p/google-web-toolkit/updates/list

is this possible with CellWidgets?

Thank You
