\listfiles
\documentclass{article}
\usepackage{pstricks,pst-node}

\begin{document}

\quad\rnode[lb]{A}{\rnode[rb]{B}{\rnode[rt]{C}{%
    \rnode[lt]{D}{\Huge g}}}}
\psset{nodesep=5pt}
\ncline{A}{B}\ncline{B}{C}\ncline{C}{D}\ncline{D}{A}

\end{document}

you can define a special macro for this "four corner" node
