Apps About our group project.

Good day,
me and my group are assigned to create an android app that can configure an internet router via wifi. the app must be able to change wifi password, change login username and password, disable someone from connecting to my wifi, reboot router and similar stuffs. My question is, is this possible without the help of a browser? if so, what shud we do and study? we are noobs in android programming and we are currently studying it. i guess it will be much easier to involve a browser in this project but we dont know how, please help..
