Thanks to all of you for your replies. I have to notice the following:
1) I am fan of Sprite Candy but its GUI system supports only the basics. For example you can't have any menus only gadgets. Besides I found some problems when using the Sprite Candy library with render tweening technique(correct me if I am wrong)
2) WinBlitz3D it is very good also but every program of Blitz3D that uses native windows user interface through DLL freezes its display output when lost the focus from another OpenGL or D3D windowed application
3) FUI3D looks nice but I didn't see a sample with GUI and 3D objects running together in the Lite version
