Implementation wise this may be possible through a hack, some OS windows can be semi trasparent , this make it possible to overlay one GUI element over the other in this case a PDF with basic scrolling handles. It should be possible with UFFI and some knowledge of OS GUI APIs. Probably much easier than having to implement the entire things in Pharo from scratch which would be ideal.

The overlay windows can change size according to the dimension of the Pharo windows so you can fool any pharo user thinking this is actually an internal Pharo window. This way even if the user resize or maximise the pharo window nothing messes up the Pharo gui.��

I have been thinking about this. I don't know if you can have a VNC
client inside the image that can be used to render a PDF app, but that
would be my first approach, to leverage all the features in the current
PDF readers.
