First of all, windows are referred to by pointers not handles.  Don't ask me 
why.

Anyhow, there is a call named FrontWindow that takes no arguments and returns
a pointer to the front most window.  Since all windows of an application are
maintained in a linked list, you can walk down the list until you find the
window you want.  

Hope this helps.
