No, there's no explicit task dependency right now.
However, there are a couple options you could use:
1. Use nested tasks for this purpose. If task B is nested beneath task A, then B is a dependency of A. Godspeed supports infinite nesting (okay, okay - MAX_INT levels of nesting)
2. You could use labels and smart lists. Give blocked tasks a "Blocked" label and create a smart list that filters out any tasks that are blocked.
