Software development in Ghana is totally down as all software been used in Ghana are foreign based, software like Sage, Quick books and even Microsoft Excel are used more often for management and business transactions, i don't see how software development is going to help you in Ghana. For every software or application that you will think of developing today in Ghana, it has already been developing abroad and have much improvement.
Games, applications and related software are not developed by individuals, usually they are companies, teams and associations that develop them, as it goes to many stages like design, development, deployment, testing and ofcus selling... This field is a very expensive and the best place to study will be abroad.
Animation have been the best choice to chose from today as most advertizement in Ghana and even our own local movies have stated using serious animations in them. For this have been the choice of many developers like zingaro and the rest, about 95% of video advertizement have animations in them
The best choice is the development of websites, this is a constant growing business in Ghana as most companies are popping each day like @Dagobert
described earlier. there is always business in this field and not many people do it, there are many companies and individuals that need website but have no knowledge how and where they can get one. This will be the best choice for you on the ICT field.
keep in mind the ICT field is a very big field. One aspect of it that pays well today have been Systems and Network Administration, basically this have to do with computer networking and management which have also been in demand in Ghana for some years now. this is one field that pays really well,
About institution of choice, We have many Universities like the UDS and KNUST, that where you get certification like the 1st degree after completion, however the core of ict training in those field above can also be obtained in NIIT and IPMC which are also affiliated to UCC and other Universities abroad.
Just go through them and ask further questions for more detail
