The statistical software R has been designed as an object-oriented programing language, by offering through the package that incorporated Tcl / Tk and Java, multiple tools for building objects using a graphical interface. The commands of Tcl / Tk are embedded in R. This package creates simple functions called Widgets, windows, menus, dialog boxes and interactive charts that can help teaching statistics and the solution of specific problems, demos and examples. It is even used as a platform for the creation of new statistical packages such as Rcmdr. This paper presents the basic structure in the creation of a Graphical User Interface through implementation in the illustration of the behavior of the Binomial distribution, F distribution, simulation coverage level of confidence intervals and the effect of the Box-Cox transformation.
