Yes, this is definitely possible with tags in awesome.
"tags" are an extension of "workspaces". But rather than being a one-to-one-to-one relation (one window is in one workspace and you view one workspace at a time), tags are many-to-many-to-many. A window can be present in many tags, and you can view more than one tag at a time.
Most of the time, I use tags just like "normal" workspaces.
The GPs use case may be solved in two ways using tags, either by viewing two workspaces at the same time (the other one is code tag, and the other one is switched between docs, browser, tests) or by having the code editor present in several tags.
