Yes, actually I even built a WordPress plugin which you can download at http://wordpress.org/plugins/bitcoin-order-form-for-mapsmarkercom/ The code is also available on Github at https://github.com/robertharm/bitcoin-order-form
Please be aware that this plugin is customized for MapsMarker.com and has not options to customize the products in the backend. I shared the code for developers in order for them not having to re-invent the wheel but to only change some form parameters in the code if they want to use a customized version on their sites.
Please check out the roadmap for planned feature for next releases of Maps Marker Pro.
