What is claimed is: 1. A decorative window muntin made by a process comprising the steps of: providing a substantially rigid non-metal polymeric planar member; constructing the planar member into a unitary non-transparent one-piece muntin having no connecting joints and a curvilinear portion; and coating the constructed muntin on all sides with a heat cured coating, wherein said heat cured coating prevents the escape of remaining volatiles from said constructed muntin upon heating. 2. The muntin of claim 1, wherein the coating step comprises the step of coating the constructed muntin with a latex paint. 3. The muntin of claim 1, wherein the providing step comprises the step of providing a polystyrene member. 4. The muntin of claim 1, wherein the providing step comprises the step of providing a polyurethane member. 5. A window made by a process comprising the steps of: providing a first pane of glass; providing a second pane of glass; providing a unitary substantially rigid non-transparent one-piece muntin with no connecting joints, said muntin including at least three ends, said muntin comprising a heat cured coating layer on all sides; placing said muntin between said first pane of glass and said second pane of glass; and hermetically sealing the muntin between said first pane of glass and said second pane of glass. 6. The window of claim 5, further comprising the step of: coating the muntin with a latex paint prior to placing said muntin between said first pane of glass and said second pane of glass. 7. The window of claim 5, wherein the polymeric muntin comprises a polystyrene material. 8. The window of claim 5, wherein the polymeric muntin comprises a polyurethane material. 9. A muntin for use in a window, said muntin being made by a process comprising the steps of: providing a substantially rigid unitary non-transparent one-piece muntin with no connecting joints having at least three ends, said one-piece muntin adaptable to conform to the window; and covering the polymeric one-piece muntin with a heat cured coating on all sides, where said heat cured coating prevents the escape of remaining volatiles from said one-piece muntin upon heating. 10. The method of claim 9, wherein the covering step comprises the step of covering the polymeric one-piece muntin with a latex paint. 11. The method of claim 9, wherein the providing step comprises the step of providing a polystyrene one-piece muntin. 12. The method of claim 9, wherein the providing step comprises the step of providing a polyurethane one-piece muntin. 13. A window made by a process comprising the steps of: providing a first pane of glass and a second pane of glass; providing a substantially rigid unitary non-transparent one-piece muntin with no connecting joints, said muntin comprising a heat cured coating layer on all sides; placing said muntin adjacent to said first pane of glass and said second pane of glass. 14. The window of claim 13, wherein the process further comprises the step of: coating the muntin with a latex paint. 15. The window of claim 13, wherein the polymeric muntin comprises a polystyrene material. 16. The window of claim 13, wherein the polymeric muntin comprises a polyurethane material. 17. The window of claim 13, wherein the step of placing a muntin in a window further comprises the step of fixedly attaching said muntin to said first pane of glass. 18. The window of claim 13, wherein the step of placing a muntin in a window further comprises the step of fixedly attaching said muntin to said second pane of glass.
