Logging query text without Profiler
Several options:


You could use SQL Server Profiler against the Workgroup Edition server from a different client tools installation of SQL Server Developer, Standard, Enterprise or Evaluation Edition.
Use the semi-documented trace flag 4032, as explained by Tom LaRock.
Evaluate third party tools like the free DataWizard SQL Performance Profiler, xSQL Profiler (free for one instance), or ExpressProfiler (BSD Licence).


My preference would probably be option (1), downloading Evaluation Edition if necessary.
