Try:

\newcommand{\mynewcommand}[2]{%
	\expandafter\newcommand\csname #1\endcsname{#2}
}

It should do the trick. The \csname ...\endcsname does the  
concatenation you desire. The \expandafter is there so that the name  
"\#1" is built first and then passed to \newcommand. I'm sure Morten  
H. could be more precise on this and give a more robust way of doing  
it...
