right click paste in rxvt

hi list
i have a question for which i have been trying to find an answer for a
long time
I normally use a windows machine but sometimes need the power of unix
and hence have installed cygwin on my machine. when i connect to any
linux machine using putty i can usually select a word by highlighting
it with a left mouse click and paste it using the right mouse click.
how can one achieve the same in xterm on cygwin.

More specifically i want to modify xterm so that i can select and copy
with left mouse click and paste by clicking the right mouse button
instead of middle mouse button
any pointers how to do that

thanks
Akash
