Node for desktop widget (or an attempt to try out a node in practice)?

Question

Webkit

For a very long time I heard about Node, but only now I came up with a small project on which you can use the node, namely, a widget on the desktop (Windows, although IMHO it should also work on Unix), which executes a certain bash script three times in a few seconds on a remote machine via ssh.
And now in more detail: I wanted to try the node in action on the desktop. I know js at jquery level. I want to make a simple widget for the desktop (a window that cannot be dragged and which is always behind all windows, optionally passing clicks through itself like a graph in networx), which would cling to the server via ssh (or http) and, executing a command, analyze and return certain data to the screen (be it a simple linux top, graph, html or picture, or even something mixed). It is desirable to do not just "to work", but "to work beautifully".
I heard about NW.js now I'm sitting and reading. Googling, of course, will help 100%, but since this technology is completely new to me, I decided to ask for advice from those who know. What to use? What are the pitfalls, etc.?

Answer 1

The prehistory is weighty, but there is little specificity in the question itself.
The direction of thought is correct.
Possible difficulties: asynchrony, modularity, tcp sockets, interaction with processes, work with system windows - it seems so.
Concerning beauty is to look towards css.
