You can get the hwnd without modifying BRL module. Just do some copy work.
C side:

#include <windows.h>
/* copied from BRL.glgraphics */
typedef struct BBGLContext{
	struct BBGLContext *succ;
	int mode,width,height,depth,hertz,flags;
	HDC hdc;
	HWND hwnd;
	HGLRC hglrc;
} BBGLContext;


HWND getGLhwnd(BBGLContext *c){
	return c->hwnd;
}

BMX side:


Import "glhwnd.c"
Extern
	Function getGLhwnd:int(c:Int)
End Extern

'test
Local g:TGLGraphics = TGLGraphics(GLGraphics(640, 480)) 'get GLGraphics
print getGLhwnd(g._context)

This works on win32. No idea about Macos (since I don't have one).
