There's a post on the GWT google group that discusses the answer. Basically you create your custom widget as normal, and inside the render function you use widget.getElement().getInnterHTML().

@Override
public void render(com.google.gwt.cell.client.Cell.Context context,
            String value, SafeHtmlBuilder sb) {
        if (value != null) {
             MyWidget widget = new MyWidget(value);
             sb.appendEscaped(widget.getElement.getInnerHTML()); 
        }
}

This is an anti-pattern. The whole purpose of cells is so that you do NOT have widgets: you are supposed to "render" html directly in the cell.
