For newcomers trying to copy this: You need to add the line

  (use-namespace "System.Windows.Forms")

before you run the application.

I think that's a problem related to the IDE and not to RDNZL.  In
LispWorks 5.0, for example, if I start the apropos example coming with
RDNZL (which also uses Application.Run) with MP:PROCESS-RUN-FUNCTION
as suggested in the RDNZL documentation it runs fine without locking
the IDE, i.e. I can still use the listener or other graphical tools
while the .NET window is up and interacting.

I don't know much about CG but I think that will be very hard or
impossible.  But that's not a problem of Lisp/RDNZL.  I think it would
be equally hard to mix a C++ program using MFC with a C# program using
.NET's windows forms.
