Thanks for clarification.

So the only possible *theoretical* way is probably:

Gtk.Window w = new Gtk.Window();
Swf.DataGrid g = new Swf.DataGrid();

class SwfControl { ... /* make Swf.Control a Gtk.Widget here */ ... }

SwfControl c = new SwfControl(g);
w.Add(c);

I understand that requirements are doubled, but otherwise development
time is also doubled ... probably it would be nice to have them working like
ActiveX work in Swf applications. There are so many nice control libraries
for .NET which look attractive to reuse and not to reimplement.
