Arabic Fonts

Need to create a font for honorifics.

Peace be upon all my friends!

I want to create my own font for honorifics, to use in my website.

The challenge is that I would like to create ligatures to ensure that entire phrases are replaced by glyphs.

Could you guide me on which is the best tool for this purpose? I am new to this, and would love to have a tool that is intuitive. Paid options will also do.
