There is surprisingly a lot you can achieve if you just change some default CSS values in Aware IM to support RTL:
direction: rtl;
unicode-bidi: bidi-override;
See this screenshot of a test form changed for the RTL layout:

I don't know how to use the Arabic text so in this example I used "Text" for label and "This is text" for the value of the input field. You can see that the browser automatically takes care of the direction.
