Rounded boxes with text inside in beamer

pdflatex

I want to have several texts in latex which are boxed in a circle or more in a rounded box.
I tried to use:

\pgfnodecircle{Node1}[stroke]{\pgfxy(1,1)}{0.5cm}
\pgfnodecircle{Node2}[strokel]{\pgfxy(3,0.5)}{0.25cm}
\pgfnodecircle{Node3}[fill]{\pgfxy(5,1)}{0.25cm}  
\pgfnodeconnline{Node1}{Node2}  
\pgfnodeconnline{Node2}{Node3}

but this \pgfnodecircle command does not allow me to write text inside the nodecircle.
I could have added text with \pgfnodebox but I really want the text to be surrounded by rounded boxes and not by rectangular boxes.

maybe you want the block environments: block, theorem, proof, and example? You can then find a Beamer style to make them rounded.

\begin{block}{Block title}
