This example of the formation of a coarse-grained DPPC lipid-bilayer was provided by Saeed Momeni Bashusqeh and uses the Martini force-field v2.0 (2013-10). In this example, the initial coordinates are generated by PACKMOL. If you prefer, there is also an example of a Martini DPPC bilayer which has been preassembled using moltemplate commands which is located in the "DPPC_bilayer_preformed" subdirectory in the examples you can download at www.moltemplate.org. (That example does not require PACKMOL.)
