There are Bahá'Ãs all over the world, in every country.
Basically, all countries in the world.
A Bahai place of worship is called: 1) a Bahai house of worship, 2) a Bahai temple or 3) a Mashriqu'l-adhkar These are three different names for the same thing.
Yes, there are homes that belong to Baha'is in Wilmette, IL, as well as a Baha'i Home for the Aged. The Baha'i House of Worship in Wilmette is located at Linden and Sheridan. See http://www.bahai.us/bahai-temple
The Bahai community is very widely spread across the world, but in small numbers. Most local Bahai communities meet in private homes, or in a rented hall or a Bahai centre, and the same places are used for worship meetings and other meetings. However specially dedicated Houses of Worship / Temples / Mashriq'ul-Adhkars (3 names for the same thing) have been built in some places. There are continental Houses of Worship (for example, the North American one in Wilmette, Illinois) and two national ones are about to be built (Congo and Papua New Guinea). Local communities, especially in the third world, may have a small house of worship or Bahai centre built with local resources, and plans for a number of smaller Houses of Worship have recently been announced in Cambodia, India, Kenya, Colombia and Vanuatu. These will be built with help from the Bahais around the world, and will be in permanent materials.
As of 2012, no country has a Bahá'í majority.
A Bahá'í believer can worship, or pray, anywhere - at home for example. However, there are usually designated places in each town or city, where Bahá'ís meet to pray, to consult, etc.
Muslims do not worship any country. however, the question may be asking about in what countries do Muslims worship. The answer is Muslims worship in almost all countries of the world, either as majority or as minority.
Several Bahá'í houses of worship were built; so far, basically one for every continent (as of 2013, the one in South America isn't finished yet). You can find a summary in the Wikipedia article entitled "Bahá'í House of Worship".

The Bahai Faith does not use any code in its scriptures, which everyone is encouraged to read for themselves. See the Bahai Reference Library for a good selection of Bahai scriptures, all for free. The Bahai community today also does not use codes, secret handshakes, etc..
It depends what you mean by "church."The "church" in the sense of a building for worship is called the Mashriqu'l-Adhkar, which is literally the place where remembance of God goes up: a plain English equivalent would be chantry. Bahais in the west call them houses of worship. There's a wiki article here:http://en.wikipedia.org/wiki/Bah%C3%A1%27%C3%AD_House_of_WorshipThe "church" in the sense of the community of believers is just called the Bahai Community or Bahai Commonwealth."The Church" in the sense of a the authorities within the community that say what's right and what's not, and what's going to happen, is called the Bahai Administrative Order. There are no priests, the authority is in the hands of elected bodies, from the local to the international level, and there are people appointed for special functions but without any general authority in the community.
