You're right. Can you think of a good example of a Tcl/Tk app that I should look at?

No way. GTK and Qt with RAD are every bit as fast, and the end result doesn't look like complete garbage when you're done. Every Tk app ever written looks like it comes from the bad old days of early 90s Unix, complete with disastrously ugly widgets, poor support for basic interaction things like focus control, clipboard, drag&drop, etc.
I suggest you take another look at GTK or Qt. They've come a long way.
