there are some people? 
i have some question about wxpython ,
can i use panel without a frame?
The simple answer is "no". The panel is not a TopLevelWindow. Top level windows are Frames and Windows. Panels typically go in Frames, although you can nest panels in panels or frames. Telling us what to do, as Ryan suggested, would be the best way to get a good answer though.
