Have a contact form split into two columns

Hi,
I always have used contact form 7 for my Contact forms and in the past i was able to split the form into two columns.
See the following link: http://www.musicbychoice.co.uk/contact/

The last version of the plugin doesn't allow me to do that.
They HTML use to be in separate columns you could style but now is not like that anymore

Could anyone tell me about a contact form plugin I could split into two columns and also created a rounded corners too.

thanks in advance,
