More important than the above comments is whether your main purpose can
even be achieved by creating frames and deleting windows. The buffers
still exist until they are killed and all of them will be viewable through
the new frames you create. It might be a good idea to try and accomplish
what you want (semi-) manually before you try it programmatically. I don't
know enough to state categorically that you can't do it, but I doubt it. I
tried to look for functions that might help you but I kept running into
dead ends. For example the promising frame-live-p in frames.el couldn't be
traced further. I must be a c language primitive. By evaluating
(frame-live-p) in *scratch* I found that it needs 1 or more arguments. A
number, string, and symbol all returned nil instead of a backtrace.
In version 22 there is a frame-selected-window function that on first
invocation returned

#<window 8 on *scratch*>

and after killing some buffers:

#<window 3 on *scratch*>

it probably requires advanced knowledge elisp or maybe even c.
