Programming languages that don't suck

Lisp, Scheme and Haskell are the obvious ones. JavaScript is a nice language. C always has its place. C# might be the jewel of enterprise.

What else is there that /prog/ recommends? I've heard good things about ML. A language that seems interesting from its Wikipedia page is Self, but I'm not too sure about it.

Prolog
Then show me a GUI application, written in Prolog.

And yes, I have used apps glued with Python. ArcGIS is a counterexample to your claims. Ruby has been used as glue code for game logic and other high-demand applications and it's certainly fast enough if you're not trying to do something dumb. Separate out the performance-demanding bits of your code, and write that stuff in C.

And if you think Python is bad because of the GIL, try IronPython, Stackless, Jython, or hell, even TinyPy. The implementation is not the language.
