There are a few analysis objects, and yes: objects are useful outside
of the graphics and UI context. Since the objects are bolted onto the
structures, you also inherit (no pun intended) the limitation of named
structures: arrays have to be pointers, or you won't be able to resize
them.

IDL has its own UI toolkit (probably based on something more or less
native). I /never/ use IDL for user interfaces, the 'I' in IDL is
pointless to me at this moment, and I don't think that will change. I
would say: just don't bother with IDL user interfaces, especially if
you already know Python and WxPython. Those are much cleaner, more
modern, and far less frustrating. And some algorithms are just plain
easier to write and read back - if you need to obtain a fair speed.
'for' loops don't kill Python like they do IDL.
