If you download Kirk Trachy's Magic button app in the Exchange, he does have an example of this. Try clicking on the first project and you will see an embedded document in Courier format.
I suggest getting it to first work with a PDF stored in quick base as a file attachment, then try to get it working for an external file.
He makes a formula text field with this format and then uses it as both side of a report link configuration.
If([File Attachment]="","No File","<iframe src=\"https://docs.google.com/gview?url="&URLRoot()&"up/" & Dbid () & "/a/r" & [Record ID#] & "/e262/v0"&"&embedded=true\" width=\"600\" height=\"600\" frameborder=\"0\" target=\"_blank\"></iframe>")
