If by "do it" you mean hide the "Warning: Applet window" message, no, you
cannot do this. Appearances to the contrary, the site you quote is not
using Java applets for their menus.

That is because there is no program that does this. Ergo, there is no source
file that shows how to do it.

We did. We told you that it cannot be done. If it were possible, there would
be a headline on the front page of every technical journal in the country
warning about it, because if it were possible, a hacker could create a
free-floating dialog in a locally spawned frame, one that appeared to be a
local system dialog, to collect passwords, personal information, etc. from
unsuspecting visitors to his site.

The people at alienmenus.com know how to do it. For learning purposes I copied
their jar from Sun's JAR cache, extracted the included .class files and used
jad.exe to decompile them. Now I have the source code to study to determine how
it was done.

If you want a lawsuit on your hands I suppose you could modify any copyright
notices and recompile the source code generated by jad. If you don't, I'd
suggest studying the technique used and replicate it in your own Applet.

By the way, while sorta nifty, their menus are not the be-all and end-all. I
loaded them on an 800 x 600 desktop (both FF 1.0PR and IE 6.0.2900) and any
horizontal menu that extended beyond 800 pixels spent it's time blinking in and
out of existance as long as I kept my mouse over the parent menu item.

(shrugs) It depends on the time of day,
the season, the applet, the site, and
who you ask, among other things..

[ Lies, damn lies and statistics. ]

Too many.  Please ensure any applet pages you
write are not amongst them.  Come back here
when and if you need to write Applet HTML and
I'll try to guide you, but you can usually
make a pretty good job of it if you read Sun's
docs on the applet attributes.

I cannot say I observed any such thing, and since they
cannot be using Java (no permissions) and were apparently
not using JS (I visited with JS disabled and the page
seems to 'work' just as much in Moz. as it does IE -
the menus are there, they do pop-up, but do not seem
to do anything.)

Speaking of JS, the applet tags mention MAYSCRIPT, which
marks an applet suitable for scripting using JS, and that
might mean another dependency.  (Not good for a navigation system).

Another interesting note is that the applets are compatible
with the MSVM, so whereas a Swing based JApplet might add
a JMenuBar and customize the JMenu, an alternate approach
would need to be taken for the AWT based Applet, as there is
no MenuBar you can attach to an Applet.

Some questions for you.  Are you wanting to make a menu?
You talk a lot about Windows, but you have not specified
the content yet.

Because, that is the first part of this thread I heard
that makes some sense.  Not that I am especially fond
of pop-up/out menus in web-pages, but I can see the
validity of the use.

Have actually seen this particular menu change pages?  
(I suspect they are not hooking it up to actual pages
for the very resons discussed in the thread I pointed
you to.  The showDocument method would be the crux of
a Java applet based around page navigation..)
