OpenGL/GLUT - Changing coordinate system?

Hey. I'm using OpenGL/GLUT. Currently the coordinate system is like this

1
2
3
4
5
6
7
8
$ = -2, 0
+ = 0, 0
# = 2, 0
@ = 0, 2
& = 0, -2
% = -2, 2

+-----------+
|%    @     |
|           |
|$    +    #|
|           |
|     &     |
+-----------+


This is EXTREMELY annoying for dynamically changing points. This is what I would like the coordinate system to be like

1
2
3
4
5
6
7
8
$ = 0, 50
+ = 50, 50
# = 100, 50
@ = 50, 0
& = 50, 100
% = 0, 0

+-----------+
|%    @     |
|           |
|$    +    #|
|           |
|     &     |
+-----------+


How can I do this? Thank you so much.
