AFAIK you can't 'pop up' windows.
You can run a "service" (the server) on your board and connect to it
with a client. The client will run on an arbitrary platform: win,lin,mac...
This is what you see when you try to configure a router:
a web server is running on the router, and you connect to it with your browser (client).
if you want to "view" the X-server running on your board from your pc (and the apps running on it),
you need a VNC server running on youe board, and a VNC viewer (client) running on your pc.
I'm confident this can be done with nano-X, but the display-less server may be a complication;
maybe you'll need some hack to use a portion of ram as "display" and point the server to it.
I hope someone else can help you more than me on this.
In my opinion, the web way is simpler in your case. But maybe i'm wrong, i don't know
what you want to display, and if it is simple to render via HTML.
