What is the easiest way to write a cross-platform pseudo-graphics console UI application?

Question

Programming

I want to write a pseudo-GUI application that will run on a GNU/Linux terminal and also preferably Mac OS X and, if possible, Windows.
The application will actively interact with the Internet through JSON and XML REST web services.
I want to write in a modern high-level language.
I have extensive experience in C#/WinForms development and a strong liking for functional programming.
I remember under DOS there was even VisualBASIC, in which it was possible to draw pseudo-graphic forms as in Windows VB, Delphi and WinForms, but I have not seen anything like this for modern platforms.
Please advise if anyone has seen this.
Thanks in advance.

Answer 1

Go (either termui), Node.js (or blessed).

Answer 2

In Java, of course,
a hundred times the experience of developing in this language will come in handy,
but in general, you can rivet the same php script on anything, run it with the console and draw with it
or in C / C ++, to be sure
