Calling maxima via dll-files on windows



I searched the web to see if it was possible to access maxima via dll files on windows, but without luck - so presumably it isn't. However, it could be nice if such an option existed. My specific interest is in creating a small GUI for maxima as an alternative to xmaxima.
 
The yacas program can be called via a dll file through the functions yacas_eval(arg), yacas_error(), yacas_result() and yacas_error(). Based on these I've made a GUI for yacas, but I'm not really happy with yacas, so I thought about carrying the idea over to maxima. 
 
Does anyone know of a similar way of accessing maxima or whether there are any plans for releasing the windows version with such dll's??
 
Thanks in advance
