I'm not quite sure what the above definition is doing that the already defined columns environment doesn't...
\documentclass{beamer}
\usecolortheme{orchid}
\begin{document}
\begin{frame}
\begin{columns}[t]
\begin{column}{0.49\textwidth}
\begin{block}{This is a headline}
This is a block
\end{block}
\end{column}
\begin{column}{0.49\textwidth}
\begin{block}{}
This is another block
\end{block}
\end{column}
\end{columns}
\end{frame}
\end{document}
I've added a colour theme just to illustrate the extent of the blocks. So the question is: "How can I make the width of the body text thinner than that of the headline?" You can do that with a quote environment inside the block:
\documentclass{beamer}
\usecolortheme{orchid}
\begin{document}
\begin{frame}
\begin{columns}[t]
\begin{column}{0.49\textwidth}
\begin{block}{This is a headline}
\begin{quote}
Here is some text that is shrunk a little bit isn't it?
\end{quote}
\end{block}
\end{column}
\begin{column}{0.49\textwidth}
\begin{block}{}
This is another block
\end{block}
\end{column}
\end{columns}
\end{frame}
\end{document}
Warsaw internally uses beamerboxesrounded which applies the bmb@transition shading to add color between the title and the body parts of blocks. Here's the original definition (found in the file beamerbaseboxes.sty):
\pgfdeclareverticalshading[lower.bg,upper.bg]{bmb@transition}{200cm}{%
color(0pt)=(lower.bg); color(2pt)=(lower.bg); color(4pt)=(upper.bg)}
Change that definition to suppress the transition effect.
To suppress the shading, redefine the blocks template using
\setbeamertemplate{blocks}[rounded][shadow=false]
The complete code:
\documentclass{beamer}
\usetheme{Warsaw}
\setbeamertemplate{blocks}[rounded][shadow=false]
\makeatletter
\pgfdeclareverticalshading[lower.bg,upper.bg]{bmb@transition}{200cm}{%
color(0pt)=(upper.bg); color(2pt)=(upper.bg); color(4pt)=(upper.bg)}
\makeatother
\begin{document}
\begin{frame}{A frame}
\begin{block}{A block}
Some text
\end{block}
\end{frame}
\end{document}

You could add
\relaxas title and if needed, also as subtitle:\relaxdoesn't work for ablockenvironment. But for this you could use\strutor (if that is to big)\phantom{phantom Title}or something like that.
