setting parent of a window

Is it possible to set the parent of a window in another application to a window in my application?

SetParent (equivalent to SetWindowLong(hWnd,GWL_HWNDPARENT)) does not work because in order to use that API both windows must belong to the same process.

Can I use hooks or something to work around this?
