OpenDCL Studio Compatability

Hello, I'm trying to build a GUI by using a third party application, OpenDCL. In order for this application to interact with DraftSight, OpenDCL adds a few functions, such as "OPENDCL" and "dcl_Project_Load." What does DraftSight need from OpenDCL to work? If OpenDCL is not recommended or just not compatible, then what alternative software should I use? A regular ".dcl" file is to restrictive for me to complete the intended GUI layout.
