Perl is very capable of doing what you need. Off the top of my head,
the p-code outline would be:
declare a two-dimensional array
iterate over columns
read data from a source and fill a column
iterate over rows
write a row of data to csv output file
If you're serious about learning Perl, you should get "Learning Perl":

Perl works on a great many platforms, but there can be O/S-dependent
idiosyncrasies; I prefer a Linux. On Windows, I use Cygwin.
