You haven't mentioned whether you are focusing on a particular educational level?
I am sure you are already aware that you will need to do a considerable literature search and use a range of resources in your dissertation.
Are you focusing only on the development side of this resource or will you be looking at research about the role of ICT and CAL in the achievement of second language learners, or both of these? Also, are you looking at supporting the pupils across all subjects or specific areas (for example, language acquisiton, science)?
The examples of resources below are a mix of these areas. Bear in mind you may not find a great deal (if any) literature that focuses on all aspects of your research, however, you can still bring points together from different pieces of writing or research and apply those to your own study.
Because Urdu is so specific I suggest you start off with quite broad searches which aren't language specific, for example, with keywords: ICT, computer assisted learning, computer software along with EAL, ESOL, English second language, bilingual pupils and so on. Also, you may want to look at research about the role of software in inclusive education as a whole?
Start by searching your library catalogue, I have included some examples of books found by searching the IOE catalogue with subject terms: computer assisted learning and ESOL.
I recommend NALDIC for the EAL side of your research and also Futurelab for the design/learning technology side of your research. I include some examples of resources below - apologies if you have seen these already.
For journal articles and conference papers you may want to look at online databases - check which ones your library subscribes to - we use the education indexes (BEI, ERIC and AUEI) regularly as they cover such a broad range of educational literature. A considerable number of articles relating to software development and language acquisition was at higher education level, however, there were a few aimed at primary/secondary level.
I suggest you continue searching as this is only a sample and you may want to use some of the information sources suggested below.
Once you have found relevant references you can check whether your library has the titles in stock or whether they can order articles/books for you by interlibrary loan.
I hope this has given you some ideas - best of luck with your dissertation.

CALL research perspectives. Egbert, Joy. Publisher:: Lawrence Erlbaum Associates, Publication date:: 2005. ISBN:: 0805851372.
"Summary: Call Research Perspectives creates a foundation for the study and practice of computer-assisted language learning and provides an overview of ways to conceptualize and to conduct research in Call. Its core assumptions are that all approaches to research have a place, and that researchers, teachers, and students all have a role to play in the study of computer-enhanced language learning. This is not a how-to-do-research text. Written by top researchers in the field, it offers an open-ended view of what educators need to know and be able to do to answer questions that they have. It is intended to be easy to read, to provide resources for readers to explore the ideas further, and to be non-prescriptive in presenting suggestions for Call research."
