Typing a non-english language (Russian) on an english keyboard?

I am wondering if it is possible to type out Russian script using an english keyboard, on a Windows 98 computer?

I am tutoring a Russian lady on how to use computers, and she has told me that in the past she has seen some sort of program that allows this to happen.

I have searched for some free software, I can’t seem to find any.

Is there any?

Thanks in advance.
