I have written GUI applications in Racket, .NET, Swing and tk, and
Racket is the most pleasant by far, IMO.
Racket performance is pretty good in general. The Racket performance
docs have more information:

Performance-wise, it depends on the kind of code. Typed Racket performs
some type-driven optimizations. Those are most useful for numeric code,
but you may see modest speedups in other kinds of code too. I don't
expect much difference for GUI code, though. See the Typed Racket
performance docs for more details:

Realm of Racket is very good, and since you already have programming
experience, you should be able to pick it up easily.
If you need a gentler introduction to thinking functionally, I would
recommend How to Design Programs:
