Just label the rows with the column names and the make one column. Then you could scroll through it that way. You just need to call SetRowLabelValue(rowNum, label). You may find this tutorial helpful (see the end): http://www.blog.pythonlibrary.org/2010/04/04/wxpython-grid-tips-and-tricks/
You could use a ListBox, but then you'd lose the label information.
