MS Word (RTF) text in nvarchar(max) MSSQL Server

Hi, 

my customer wants to have the possiblity to use MS Word to enter Texts that will be related to a dataset in MS SQL 2014 Standard. The RTF text will be stored in a nvarchar(max) field within this dataset. The reason why it should be MS Word is simple: It's got a very nice user interface when it comes to grammar and orthographic correction. 

Questions:

1. Is it possible to create a "writeback" into a table from Word into MS SQL Server?
2. Is MS Access needed for this? 
3. Is MS Excel the better option for this task?
4. Should I rather use SSIS (Integration Services)?

Thank you for your opinion.
