Redirecting output to Command Window

I'm trying to find a way to redirect output strings into different forms in an application that runs in a console window.(Windows XP)
I'm fine with Java, C, C++, C#, Perl, and Python.

The target application has fields in standard positions, and I only need to put strings in it.
I'm in a data entry position, and trying to automate my work.

Maybe I'm not explaining this right.
I need to parse and excel document(no problem) then input the info into a order management system that only takes input through some kind of ncurses-esque interface.
I do not have access to any of the inner workings of the the order management system.

The input fields are always at the same place, so setting the cursor by pixel position, or just giving that window focus and arrowing/tabbing around will work.
