Symbols instead of numbers on first row of keaboard?

I program a lot and it bothers me that numbers are default开发者_JAVA百科, not the symbols on the front row. I would like to try the other way (And, no, I don't want to switch to Dvorak). How to configure Emacs (or whole Ubuntu) to do just that?

Please note that I don't want to mess existing shortcuts I use like CTRL+1 etc.

Here's how to do it:

 ; Keyboard Remapping
 (global-set-key (kbd "1") "!")
