The front grille on the Solstice and the Solstice GXP are the same except for the color. The NA cars have silver grilles while the GXP has black Grilles. The grilles are held in place with plastic tabs but two of the tabs on each grille have a metal clip that locks it in place.
This article contains instructions on how to remove the front grille without removing the bumper. At the end of this article are samples of various different aftermarket products and painted/chromed treatments.
The following instructions for removing the grille were originally posted on the Solstice forum by Karr1008. .

This is what it looks from the inside, I inserted a small cam to check for the metallic clips...oh there they are.
The brake duct grille around the fog lights is very easy to remove. Just hold it firmly and pull straight off.
Here are pictures of other grille treatments from other members:
Chrome Mesh Grille on Black07Solstice
These are available from Grille4U. They look Great but they only carry the main grille. They do not have the break duct grilles for the GXP.
CarID has a few different options. Again, they do not have the brake duct grilles for any of these options.

Race Mesh Grille
Lund Makes a horizontal framed perimeter grille available from Automotive concepts.
Aftershock makes a 2 part recessed grille. The frame and the grille can be painted two different colors. Installation of the aftershock grille requires trimming of foam bumper piece. The aftershock web site seems to be down as of the time of Feb 2010 but perhaps they will bring it back after the spring. If you are interested in their products you can contact Rudy directly on his email email@example.com.

One other option is to paint the grille Chrome. Although a bit expensive for paint, KillerChrome allows you to recreate a real Chrome look on plastic without using a spray gun. As of 2010, their kit sold for $115. My only concern would be how well it would hold up.
If you like this look and have the money, you can have the plastic "chromed" by this. The cost for this process varies from $300-800 plus shipping. You need to supply the grilles. From what I've heard, it can take up to 3 weeks if not longer to get them back.
Companies that provide plastic Chrome coating include:
Again, the same question applies as to how well this plating process would hold up and whether it would chip as a result of road debris.
