I have finished creating the board layout except all the GND wires.
What I want is that all the free place on the board will be part of the GND
ground plane.
How should I do that?

Next problem, I have text on the bottom where the ground plane should
come.
How can I create a clear rectangle around that text. If I create a
poly around the board the text is still there but completely enclosed.
It depends on what layer you put the text in and how your CAM job
outputs. If the layer that the text is in is output as part of the
bottom silkscreen then it will not interfere w/ the pour since the
silkscreen will be printed on top of the metalization.
If you are trying to put text into the same layer as the ground pour
then the letters in the text will automatically be isolated from the
plane just like vias, pads, etc.
If you want a nice rectangle around the text, you can draw draw a
rectangle on the bRestrict layer that encloses the area occupied by the
text to prevent the copper pour from filling that area. This will
produce DRC errors since the text itself is within the bRestrict area.
Once these errors are marked as approved DRC will not bother you again.
Enjoy,
