You could just arrange the two windows side-by-side.
Or, you could use QuickLook to have it float there. Just select it in the Finder and hit Space bar. Move the Quicklook window wherever you'd like.

Thanks Barney, the quick look didn't work because the app I am editing won't allow an open window in front of it, but re sizing the app to be edited does allow the quick look window to remain open next to it.
