Here is what I think I is the smallest program to open a window..

[Application.Run (new "Form")]

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

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

before you run the application.

However, started from an emacs buffer, this locks up everything until the window is killed.

I can put this in another Allegro OS process by doing this.. (mp::process-run-function "myprocessname" [Application.Run (new "Form")])

But this also locks up everything until the window is killed.

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.

How can I do this in rdnzl? Can I mix CG and rdnzl?

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.
