Creating Reports

What needs to be installed on a workstation in order to be able to create
reports for reporting services?
I have Visual Studio .NET installed, and having installed the reporting
services client noticed it had appeared as an option in VS.
A colleague installed the reporting services client who didn't have Visual
Studio .NET and doesn't seem to have the ability to create a report.You need VS. I've read here about other software to generate the RDL,
but VS makes it much nicer.
