Something I played with is make a dcl based on Autocad objects so for Radio button dcl it would look like the attached. it has radio buttons and a edit box example. You will see it has Blocks and text. In the case of the edit boxes uses the scale for the size of the box.
In radio button follow prompts just select buttons and labels when asked use window etc, the dcl should display.
This is real time to make a dcl.
