Wait for a specific command call

[Matthias]

Hi,

I have written a command displaying a list of buffer, the user can
edit it, etc. I want this command to end (or return) if and only if
the user call `quit-window'...

It seems that it is possible using `recursive-edit' but the manual
says `Most applications should not use recursive editing, except as
part of using the minibuffer.'

Any other idea?

Thanks for your help.
