System and method for synchronizing software execution in a computer system. Threads or processes executing in the computer system are synchronized via various types of synchronization objects. User input indicating a desire to specify a synchronization object operation is received, specifying a particular type of synchronization object on which to perform the operation, in response to which a graphical user interface, is displayed which is useable to specify a plurality of synchronization object operations, e.g., that are specific to a specified type of synchronization object. The graphical user interface enables the user to select a desired operation to perform on a synchronization object. The user may also specify additional configuration information for the operation. In response to the specified synchronization object operation, program instructions that are executable to perform the synchronization object operation may be programmatically created, and may subsequently be executed to perform the specified synchronization object operation.
