No -- see FAQ 12.15:
"The advanatage of this setup is that it is possible to install multiple R versions in parallel and they all will be fully functional as long as the Current symbolic link points to the currently used version."

No, the GUI embeds R so a given binary works only with a very specific version of R. You can *compile* the GUI for any R version but the binary will be tied to a specific R version.
