Unfortunately I don't think Blitz (natively) allows you to right-justify text in textfields or textareas.
I thought you might be able to set the right-justify (ES_RIGHT) flag through the WinAPI, but it seems like you can only do it when you create the textbox. You can't modify it afterwards. So if you absolutely needed to, you could probably create your own with CreateWindowEx, but it wouldn't be a Blitz gadget, and you'd probably have to manage it yourself.
From MSDN:
Edit Control Styles
To create an edit control using the CreateWindow or CreateWindowEx function, specify the EDIT class, appropriate window style constants, and a combination of the following edit control styles. After the control has been created, these styles cannot be modified, except as noted.

ES_RIGHT
Windows 98/Me, Windows 2000/XP: Right aligns text in a single-line or multiline edit control.
Windows 95, Windows NT 4.0 and earlier: Right aligns text in a multiline edit control.
