Screenshot program for Linux on what to write?

Question

linux

For the purpose of self-development, I want to write an application program for desktop Linux (later I can transfer it to Windows). Go seems to be faster, and there are more libraries in Java. What is better and what can be the difficulties?

Answer 1

For self-development, it is better to master a regular screenshoter.
And there are no difficulties, and there is no need to look for stupid pretexts to discuss "go vs java".

Answer 2

On desktop Linux, they usually write on what the main DE runs on - for KDE it is Qt, for GNOME it is GTK. However, nothing prevents writing in this or that toolkit and in other environments. No one will drag a toad or go bytecode interpreter into the system (I don’t even know how it is processed) for the sake of such a modest thing as a screenshoter.
