First, Thank you for your support. And it's very kind of you to help us translate WinISO Standard 6 into your native language.
We use the QT Framework.
What's more, QT language Pack is .ts file format, you need to download a tool which is named QT Linguist to open it. The download site you can refer to the Language Tool.zip.
Here is the QT Framework tutorial for you.
Note: All of the translation format should be the .ts file. So please send the .ts file to us. Thank you.
