That's right.  But I would start with something simpler.  Say just
"QUICK CLUSTER x y z".  The syntax parser can be a bit challenging
so keep it simple to start with, and add the options later.

You'll need to write a function of the form:
 int cmd_quick_cluster (struct lexer *lexer, struct dataset *ds);
and register it in the file src/language/command.def

I suggest that you look at some of the existing examples to get
an idea of how it works. reliability.c is probably a good example.

     
     also: I have no experience about coding GTK+

The first step will be to get the command written.  You or someone
else can write the GUI for it later.

Good luck.
