Dialog box for creating a directory

[Roy Edgar Hansen <Roy-Edgar.Hansen(at)ffi.no>]

Does such a thing exist?

I want a dialog box such as dialog_pickfile or FSC_fileselect (from
David Fanning)
to pop up during my processing for creating a new directory where all
the files from
processing should be stored. It also would be nice if there was the
possibility to show
the directory structure... (such as in the above mentioned).

I know this is not far from a number of the examples at
www.dfanning.com,
but if someone has done exactly this (or knows how to) already....
