Opening a window on Windows?

[Ian Wood]

After a few searches of the list and the docs I've found no answer, 
so...

I want to open a window to show the user a load of new JPEG files that 
have just been generated by my app.  On Mac this is easily achieved 
with a couple of lines of AppleScript.  Is there any way of recreating 
this on Windows?

The irritating bit is I don't need it on Mac, as AppleScripts allow me 
to do all the post-processing automatically anyway.

Thanks in advance for any tips,

Ian
