MySQL Workbench is not installed INTO WAMPServer, its a free standing MYSQL tool, but yes you can install it quite easily and it will see the MYSQL Server that comes with WAMPServer.
Although I install the .msi version.
Just remember not to install another MYSQL Server, and install the pre-requisites before installing Workbench i.e.
Microsoft .NET 4.0 Framework
and
Microsoft Visual C++ 2013 Redistributable Package (MSVC2013)
