You can use a progress bar and use a loop to update it (see an example here. You can modify it for a while loop by using the Quotient and Remainder function).
You can also use an animated GIF (also known as a throbber) and show and hide it using property nodes (you can put it in a tab control and show and hide the tab). You can find some free ones by searching Google.
You can also try customizing the control I posted here which uses a flow animation, not dissimilar to what Win98 used to have when it would load up.
