What is the fastest way to check hud code result?

[kung foo man]

If you use WinSCP and Notepad++, the file is send to the server automatically. Then, as you say, restarting the map is rather quick to see the changes.

But I also remember some tools for creating/designing HUD's, can't remember the names tho

I usually just tinkered around until it worked they way I liked it.
