Are you speaking of firewall settings and such?

Firewall settings cannot prohibit specifically X11-forwarding with ss=

PuTTY is a commonly used Windows client that won't accept X11 forwardin=

because it is text only. If the OP's workplace uses it, that's a pretty
good reason for not using a GUI.

Are you sure PuTTY does not accept X11 forwarding?

I often use PuTTY to access some servers where I have shell accounts.
The configuration dialog has an option "Enable X11 forwarding". With it
checked, and the Cygwin X11 server running on my laptop, if I type e.g.
"xterm &" in the PuTTY window, an xterm, running on the server, displays
on my laptop.

For that matter, with cygwin on the Windows machine one can use the
cygwin command-line 'ssh' program with X11 forwarding.

I'm still not clear as to what the OP was discussing in the comment,

... when using SSH where you can't forward the necessary ports.

I'm also interested in how their program is made portable between
Swing and non-GUI interfaces:

Fn fact my application does have a Swing GUI, but sometimes there is no
way of having an X-Window

That sounds like a good piece of engineering and I'd love some
pointers.
