A package manager could help with this.

For example, install Homebrew:

  http://mxcl.github.com/homebrew

Install GFortran and R:

  brew install gfortran
  brew install R

You might be able to skip this step and use the R binaries from CRAN---the 
only caveat I can think of is that Homebrew doesn't build a Universal GTK+ 
(it gives you x86_64) and CRAN R might want to build both i386 and x86_64 
versions of packages.

Install GTK+:

  brew install gtk+

Run R and install rattle:

  install.packages('rattle')

Hope this helps!
