How to create multi-column data entry form using CSS in Asp.Net?

Question

While converting a desktop application to a web app, I've run across my ignorance when attempting to implement a multi-column data entry form using CSS. I'm resolved to avoid using tables for this type of thing, and while I found a good reference to laying out a data entry form, I can find nothing that applies to multiple-column layouts like this one:

Can anyone point me in the right direction?

Please note that RedFilter's answer has a different tab order, which I have demonstrated in the screenshot below:

CSS (cross browser friendly)

p
{
 margin:1em 0;
}
label
{
 float:left;
 width:5em;
 text-align:right;
 margin-right:0.5em;
}
input[type="text"]
{
 width: 10em;
}
.left-column, right-column
{
 float:left;
}
.left-column
{
 margin-right:1em;
}​
.textarea-label
{
 float:none;
}
textarea
{
 height:5em;
 width:35em;
}​
