Which language to choose?

I would like to ask people’s opinions as to which language is most similar to javascript? I don’t program for a living, but I have been learning javascript in my spare time. I would now like to have a shot at making a desktop application, and I think it would help to choose one which is most similar, if at all possible, to javascript?

e.g. python, ruby, C#, visual basic … I have no idea and haven’t had much luck googling this

Thanks
