Try vtcl, just make sure you only enable the available packages. You also need to wrap arounf the generated tcl to run init_tk & a vwait exit_var.

I think I preferred SpecTcl to VTcl but both of them produced code that was unmaintainable. They both use their own approach to maintaining the widget namespace and I found them both equally unwieldly if I had to go into the files and do manual tweaking. Not to say they won't work for you, just letting you know what my experience was with them. They both ran under Quartus II's Tcl engine but you need to add init_tk to their top-level files first to get them to work.
