There are no languages that allow you to load a PDF, because that's not what languages do. You need a library you can use in your application that can load the PDF and allow filling in boxes, like GdPicture.NET[^] or GrapeCity's library[^]. ...

You first need to find out which platforms the app is to work on. Once you have that list you can research which frameworks can support them all. See Cross-Platform Mobile Development in Visual Studio | Microsoft Docs[^] for one suggestion.
