[Pmw] Showing a Dialog to while main window in working

I have a Pmw.ScrolledCanvas that shows some informations taken from an xml file that i have to dowload every time i open my application.
But dowloading the files takes some time and I need to give some feedback to the users (now i wait about 3/4 seconds and than the main windows get opened but in the meantime I have no feedback).
How can i show another window that says: "wait some seconds while I perform some operations"?
I like the solution of the Pmw demos (the TopLevel) but i need your help to construct that one!
Thanks to everyone
