Which control to use

Question

I have to copy an old sales-terminal application. The application works like this: you have 4 columns. In the first column you enter the article-numer and press enter. The other 3 columns are then automatically filled with values from a database and you jump into the second column to enter the amount of the article. You then press enter to cycle through the columns. When you reach the last column and press enter, a new row is created. Any ideads whihc control / control would be best suited to create a behavior like that ?
