R aside, tcl/tk itself is far from dead. Although not as popular as in its heyday there is still a core group that works on it and keeps issuing new versions. The versions are quite a few years apart but on the other hand they tend to have major improvements to them which would seem to justify a longer cycle. In terms of the tcl/tk community, new or updated packages for tcl/tk keep coming out. Looking at some of the tcl/tk packages that I have used in the last year I notice that several of them have a last release date of this year. Also at least some books on tcl/tk keep coming out, the tcltk mailing list is active, there continues to be tcl/tk conferences and there is a very active tcl/tk wiki.

The above was for the tcl/tk language only but if we look at the tcltk R package then its bundled with most versions of R so its the easiest way to have a GUI with minimal installation hassle on most platforms. On Windows and most Linux distributions just issue library(tcltk) in your session and you have it with nothing else to do in terms of installation. Furthermore there is a reasonably large infrastructure of R packages either built on tcltk or that can use tcltk as well as a number of addon R packages that can ease development.

If you can't decide on which GUI toolkit to use have a look at gWidgets. It provides a common layer over multiple GUI toolkits which subject to some limitations based on which features were used lets the user switch at will among the various toolkits.
