Tclcsound is both a frontend and language wrapper
for Tcl/Tk. With it you can control csound using
tcl scripts. Two basic applications spring to mind:
GUIs can be built using Tk commands; A csound server
can be set up to receive incoming commands via TCP
from a remote client.

My motivation was actually to provide the infrastructure
for Cecilia to use the csound API. However, this thing
is proving to be useful for applications beyond it.

I have not yet announced or explained it in the csound
list as I want to complete a basic set of commands
(I think it's done now, but not committed) and I want
to test it a little more, providing examples as well.

You should be able to build it, if you have Tcl/Tk
(8.4 or later recommended) installed and define
buildTclcsound=1. I have tested it in all three platforms
and it seems to build OK.

You can find an example script for cswish in
examples/tclcsound.
